It's probably as another commenter alluded below: people are taking this weird position of "I haven't personally lived through it so it must be literally any other explanation" when someone who has direct experience with the type of behavior exhibited points to it happening, live and in living color and says "this is a problem for me as a member of this group".
I couldn't ever in a hundred years imagine telling a blind person who says "this is my experience as a blind person" they're wrong, or what they live through on a day to day basis isn't valid because I, a person with full vision experience it differently.
But here we are. Reading some of the comments in this thread has me cringing just as much as reading the claims alleged in the article [0].
