I think it's funny that some people keep posting whatever horrible or stupid thing Trump does and expect this to be the thing that makes Trump supporters have an epiphany and realize that they are wrong. There are plenty of people that stood by Nixon through Watergate, and still feel that he got a raw deal. Hell, there are a lot of people that think the South was right to keep slaves, and that Hitler had the right idea. Now it's true, that many of the people that think these things are also Trump supporters, but that's not all of them. The sad thing is that his supporters that don't believe those things can't see the light it casts them in when they throw in with that lot.
Point is, they already know all the horrible and shocking stuff you're telling them, so why bother anymore? They are either okay with it or tune it out and live in blissful ignorance. Pointing out how stupid or wrong you think they are only proves to them how right they are. You're going to have to make your peace with the fact that some Trump supporters are people that just disagree with your political beliefs, then block them or let them be. Chiding and attacking them will never achieve anything at all. It won't convert them, it won't convince them, it won't result in any productive and rational political discussions, it won't have any beneficial effects whatsoever.
Take all that time and energy you spend feeling superior to others and telling everyone how wrong they are because they don't think like you and put it towards getting the people you want to lead us elected. Volunteer to work for a candidate you like, make calls, get voters out to the polls, whatever.
As with everything in life, put your energy towards positive endeavours and get positive results. Put your energy towards negative efforts and everybody loses. It's really a pretty simple equation.
