To expand a bit on what I said, I think if you have a circle of friends that you mostly communicate with online, and they're the ones that send you links and things, that group will be led by whomever has the strongest opinions. That person is likely to be the most extreme member of the group simply because extremists (relatively speaking) are more likely to hold and espouse views. A whole bunch of people don't really have strong views, they just bob along with the tide. So basically you end up being dragged by a lunatic in the direction of more lunatics. Then you end up screaming incoherently at someone who doesn't wear a mask and calling them a murderer and wondering why people think you're a weirdo.
