Perhaps someone has a strong opinion about a thing. They -know- they are right, and every news source is wrong. Until they find one also right. So far, we agree, that's what they want to hear.
But they keep turning to this source, who is spreading wild theories and untruths in other facets. But they were so right about issue X, they must be right about this too!
I think this pretty much sums up why so many 'conservatives' ended up unvaccinated. I cannot imagine that they set out wanting to hear that vaccines are unsafe or will give you microchips. Something/someone they trusted led them down this awful path.
As much as I support free speech, the last few years have really shown me the dangers of it, as well. But how can you regulate? Any arbiter is going to have a bias.
