It boils down to figuring out if we believe what we believe because it's what we want to believe.It's not just the mainstream media. Media in general sucks. You have to look at numerous sources and try to find the right of it in the middle, according to your best guess and trying to eliminate one's inherent bias.
Over the holidays my sister in law went on a Donald Trump rant about how he mocked a "special needs" reporter. She has a special needs child. So that really resonated with her. She literally hates Trump. I think at this point, if I tried to make the case to her that Trump likely didn't even know the reporter was disabled, it would likely just **** her off because I'm trying to deprive her of her righteous indignation. She wants to believe every negative thing about Trump, true or not. She won't have any of it not being true even if it's false.
How many more are like her?
