I've been saying this for years. You don't have to look too far to see it happening in all aspects of life. Take Fakebook and twatter, if your views fall outside the lefts views then you get shot down and called a racist, a bigot, a far right extremist... I always try and approach things from a logical point of view and leave "feewings" out of it, so I've just stopped offering my opinions on Fakebook and Twatter.
I was right about Brexit, I was right about Trump in '16, and I'm calling it again. The Shy Voter Phenomenon will strike again and leave the left scratching their heads and calling names.
I've had a similar experience so now if I'm posting on those platforms I try to keep it light and wrap it in humour to get a message through. Many people can process a meme, but if you use too many words and need them to think a bit it is too much effort for them. If you look too partisan or land on a trigger then they will attack.
That's one of the reasons I like HIVE - people here are more open to ideas and will actually read stuff, and think for themselves!
Me in 2016: - If you spend the next few years telling people why they voted Trump instead of asking them; you're going to get more Trump.
