For many people, it is a cultural war. You are either "with us" or "against us".
Online media and online narratives are written in such a way that anyone outside your own group is perceived as evil. The filtering bubble effect of closed communities ("safe spaces") often aggravates the situation. I have seen people with balanced positions turn to the far right and others to the far left in knee jerk reactions to negative experiences.
What you hear is the loud minority of a minority. Racism and sexism against white males do exist. The people who hold those values are just as bigoted as any other racist or sexist individuals.
Most well rounded and balanced humans won't tell you that any demographic is "evil". In fact, most people just want to spend their days without thinking about others.
This. We must break down own issues and barriers to truly connect to others.
