I think most of the legitimate reasons the Left has to hate America and most of the legitimate reasons the rest of us hate the Left all stem from the same power elite.
Through political control they foment wars they have no intention of winning, and through consciously bad policy they keep a sizable segment of Americans permanently down.
Through their control of education, they teach the lies that divide us, and also ensure that most students graduate at all levels less able to think than they had been. Much of “education” now consists in learning to see what you are told to see.
All of us have a common enemy. I continue to believe a coalition of the sane should be possible.
