It is uniform enough in the sense that I don't experience the discrimination people experience due to being non-white, or poor, or gay. Maybe I experience discrimination as a white man, so far I haven't been aware of it, and if I were able to decode it as such, that would be a valid intersectional study. I posit for example that were I to live in say, Japan, I would experience discrimination due to my race. That the article seems to address mostly western if not american academia is valid, imo. That it "demonizes" white men? Way less so.
My point overall is that not everyone is on the plane of existence you're on. For a cis-gender heterosexual white man that has reaped all of the privileges of being so it's probably pretty easy to see your perceived privilege talked about so patently. If you're someone who hasn't uniformly enjoyed those privileges this language is probably triggering. I don't think that intersectionality is about demonizing white men, but I do think it struggles with phrasing that is eventually used by some people to communicate that message.
I perceive some of my privilege, which is that I am not subject to non-white racism, etc... I have a few crosses to bear otherwise (autistic, bipolar, chronic illness, immigrant), and I can relate to being in the minority quite well too. This is actually why I find intersectionality a productive lens. I can be both privileged and discriminated against at the exact same time. I can be both respected for my technical skills by virtue of my looks, and in the same field be discriminated because I communicate differently. Being white doesn't shield me from all discrimination, but it shields me from some.
Intersectionality is a productive lens to view societies problems through. My experience is largely the same as yours, though slightly different circumstances. The problem in a lot of online, and in real life, discussions is that the intersectional ideas people have been exposed to are through amateur activists who don't have a view on intersectionality beyond themselves. This isn't really new in social paradigms, to my knowledge, people often recognize the struggle of others definitionally but fail to recognize it in the person standing in front of them. The experience of which is probably not pleasant.
You asked why people get triggered over this, this is my hypothesis. Don't take that for me not liking intersectionality.
appreciated, and indeed, people often have a hard time empathizing. One reason why I both enjoy twitter in order to connect with some communities, and the discourse never really feels fulfilling.
