A study by researchers at Oxford University concluded that sharing fake and junk news is much more prevalent amongst Trump supporters and other people with hard right-wing tendencies.
The study, from the university's "computational propaganda project", looked at the most significant sources of "junk news" shared in the three months leading up to Donald Trump's first State of the Union address this January, and tried to find out who was sharing them and why.
"On Twitter, a network of Trump supporters consumes the largest volume of junk news, and junk news is the largest proportion of news links they share," the researchers concluded. On Facebook, the skew was even greater. There, "extreme hard right pages – distinct from Republican pages – share more junk news than all the other audiences put together.
What kinds of social media users read junk news? We examine the distribution of the most significant sources of junk news in the three months before President Donald Trump's first State of the Union Address. Drawing on a list of sources that consistently publish political news and information that is extremist, sensationalist, conspiratorial, masked commentary, fake news and other forms of junk news, we find that the distribution of such content is unevenly spread across the ideological spectrum. We demonstrate that (1) on Twitter, a network of Trump supporters shares the widest range of known junk news sources and circulates more junk news than all the other groups put together; (2) on Facebook, extreme hard right pages—distinct from Republican pages—share the widest range of known junk news sources and circulate more junk news than all the other audiences put together; (3) on average, the audiences for junk news on Twitter share a wider range of known junk news sources than audiences on Facebook's public pages.

Please excuse me for going off-topic here, but I'm rather curious about something.
I dove into some biology articles following a previous story about epigenetics, and found myself confused about Lamarckism. Not as to whether it had any merit; I am not a biologist and do not claim to make any judgements as to the merit of one man's work over another's.
No, what was confusing was the extent to which the authors wanted to make damned sure nobody thought that epigenetics even smelled like Lamarckism. Given that the overall summary of it was the idea that individual organisms make adaptations to their environments, and that those adaptations are heritable, all that I can assume is that I'm missing something.
I know genetics doesn't work like that, and that adaptive pressure applied to generations of individuals with randomized collections of phenomes is an explanation that better matches reality. But if we can inherit behavioral, social, and apparently even gene methylation patterns, how is that fundamentally not Lamarckian? And why is it so damned important that I understand the distinction?
My guess is that the answer lies in a combination of political history and the details of Lamarck's conclusions. I'm hoping you can provide some answers, Thexalon, since you have invoked the name and clearly hold the same opinion as to its validity.

"Lamarckism" was a mostly honest attempt to provide a mechanism for variation and heredity before it was accepted that those things were anything outside the realm of God. Lamarck ended up of course being mostly wrong, although some of his idea lives on as epigenetics. The reason that so many in the field are so adamant about separating themselves from Lamarck is that his ideas were almost invariably misrepresented to further personal agendas, for instance the example of Lysenkoism given by the AC below your post.
If you're curious about the subject and want to fill a few holes in your knowledge, the book Blueprints: Solving the Mystery of Evolution by Maitland A. Edey and Donald C. Johansen gives a nice history in layman's terms of how the idea of evolution evolved (although they occasionally bog down in "dialogues" attempting to hammer down a point - a minor personal gripe - for one who needs it that probably helps a great deal). The book is almost worth it for the last chapter alone.

As Joe Desertrat indicated, what they really were doing was making sure their theory didn't smell like Lysenkoism.
First thing to note here is that gene methylation is actually the most credible example of potential epigenetics inheritance. Those others are based on some very weak science.
Further, just because a change has occurred in a child organism due to epigenetics doesn't mean that it is an inherited trait. Those can be merely environmental as well with future generations unaffected by the change.
Finally, Lamarckism is a theory about overall genetic inheritance, not merely the inheritance of a small number of traits. We know it's not true in general.

I thought that the inheritance of behavioral and social traits was self-evident, and hadn't thought much about what science may have been done on the topic. I might be thinking more of language and education, which aren't normally considered "inherited" characteristics but which I believe behave in a profoundly evolutionary manner. Not that I was suggesting that any of this is biologically encoded rather than learned throughout an organism's lifetime.

The cultural analogue might be immigrants from some part of the equatorial regions who don't celebrate any sort of winter holiday move to the Arctic Circle and start celebrating Christmas. Does that mean that there are genetic changes in any subsequent children as a result to celebrate Christmas better?

Of course it doesn't mean genetic change. But given Lamarck's time in history I really doubt any of it had to do with genetics.
The profound difference is, as you say, that adaptation during an organism's life is passed down to offspring rather than randomized variations resulting in different biology that win out over generations of natural selection. The question is: does the evolution of knowledge more often follow the former pattern or the latter? How often do we humans get it right and pass the truth on to our children, and how often do we just generate a huge number of hypotheses for only a few correct ones to survive?

To the contrary, it does. Lamarck and Darwin didn't know how traits were stored in the organism, but they were quite able to speculate on how those traits were passed on.
It follows neither pattern. The key difference is that knowledge can become greatly modified over the course of a single human's lifespan (even in the days before civilization and the potential for massive technological progress) and can be passed on by a variety of means other than inheritance. Meanwhile inherited biological traits remain very similar as they are passed on. The genetics of a grandchild is not very different from that of the grandmother, but the knowledge and beliefs can be very different and come from sources other than the grandchild's ancestors.
