I will need to look that up since it is a new phrase to me.......

"the action or practice of publicly expressing opinions or sentiments intended to demonstrate one's good character or the moral correctness of one's position on a particular issue."

Yes, the "Me Too", the "Black Lives Matter", the "Bethe1To", and the anti-bullying campaigns have all attempted to address the facts that sexism, racism, homophobia, and inter-personal violence have real consequences for real people. Shining a light on what some people dismiss as 'non-problems' and 'hype'. Freedom of speech also has opened up the discussion to non-violent ways to protest conditions and unjust treatment.

That's a good point. Racism and bigotry cut across all ethnic backgrounds and using epithets such as the "n-word" are very much unacceptable in any context. It really is about time we all became members of the Human Race and stopped thinking of ourselves in our particular cultural and ethnic contexts.

I am not qualified to answer that. I don't see the issue as finding fault with white people or white men. Just particular people: individuals who are hateful, bigoted, and hiding behind the safety of a keyboard or actually caught on camera in the light of day. I think you are referring to the somewhat controversial term 'reverse racism' and that's another subject, and one that many people (like me) think of as counterproductive.
