This seems contrary to my experience, could you provide some examples?
Obviously each of us only sees a portion of the internet, but from what I've seen it seems like most of the stuff you are describing has been aimed at people described as SJWs, not perpetrated by them.
We may be indeed seeing different parts of the Internet. I don't disagree there are people you describe who show the characteristics I mentioned in the post. I mostly try to navigate as far as I can from those parts of the Internet.
If you want examples of problems with SJW, I think it's best for me to link SSC:
That's about the only source I know that a) points out the problems, b) stays civil while doing that, and c) does not commit the same "crimes". Many other complaints I've seen about SJW are done by people not better than the group they're criticizing.
I may not like the people in that Donald Trump subreddit, but trying to blackmail the staff with doxing threats is extremely unethical, and as blatant as it gets.
