Here's what happened. Somebody posted a link to a PhD thesis in mathematics which was not at all written in the style in which math PhD these are written. Somebody else commented that this is great all math PhD these should be written like that. Then, I pointed out that the author of this thesis (a black woman), wrote a piece on a blog of the American Mathematical Society website saying that all the white male in the math departments in the USA are the problem, she wants them out and they should all resign.
Then various people started down-voting and attacking me. I replied to their attacks and defended myself. This amounted to "ideological war" according to some moderator. Also, since I did not use this account for making lots of comments, it appeared to the moderator that this account was created to primarily to start flamewars. The people who attacked me in a very nasty and personal way did not suffer any consequences since they had more comments hence their accounts looked more legitimate.
So yes, I feel like I've been the victim of an injustice.
