I think I can say that I also share similar feelings to what you mentioned, but I am afraid if you simply say you hate them, you could be doing things very similar to those you hate.

There are two factors behind most of those things.

1. Judgements made not based on context.
2. Laziness for thinking serious before making judgements or supporting the judgement.

Hate speech, racism, word can be violent, etc are real, but whether they are being conducted should be judged basing on the real context, not just because some "keywords" are used.

When a misjudgement is made, originally it should be correctable simply by a debate or otherwise some communication. But often times, the human tendency of behaving in the way so that one appears to belong or bandwagoning make the situation snowball out of control.
