I think a sizable section of Trump supporters are hopelessly lost and will never be brought back to a fact-based reality. I truly think so.
I also think they have always been this way, that simply put around 20-30% of our nations population is susceptible to this kind of gaslighting, and always will be.
I think these people should simply be written off, there is no capability to change minds and hearts of certain types of people. It can't be done. Just look at a few of the "true believers" here in this forum.
Instead, the focus needs to be on the apathy in America, those that don't care enough to do anything. We need to get back to our education system and work with younger generations to develop critical thinking skills, a civic sense of duty, a better work ethic, all of these things that are educational/social/economical problems (poverty, missing fathers, education reform...ugh the list is long.)
Tough work lies ahead.
