...Now it seems that everyone must not only tell you where they stand on issues, but they have to tell you why you're wrong for not taking the same stance. Day after day with the smug condescending memes, fake news pieces from whacked out websites, pointless hoaxes that Snopes debunked years ago ad nausem. After a while it just gets on your nerves and you either join them, drop out, or go insane.
What you are describing is really the propaganda battle in a cultural war that the Liberals didn't know existed before Trump was elected into office, and the mainstream Conservatives, while aware, didn't realize how hard it would turn on them and bite them in the butt. This war has been going on a long time: e.g. Powell Memorandum in 1971, and if you count the white nationalism/supremacy part of this - it goes back to colonial times and the advent of slavery. Trump spoke to these people and his win has emboldened them even more than before. They have mastered the tools of social media, and will try to destroy you if you do not align with their world view.
