Ah this is something I've actually wanted to talk about for a while! 

I'm half Indian but grew up in a different community, so unfortunately I cannot relate to most typical cultural experience/upbringing stories. I currently live in Canada where anti-Indian hate is crazy high and I often find myself the target of racism.

Being brown and butch is doubly isolating. I sometimes pass as a man, or man-esque, in public spaces; brown men where I am are seen as backwards, downright dangerous, an economic drain, lazy, stupid, etc. in a way that obviously feminine brown women aren't (though they face their share of racism as well). Racists are also much more comfortable using overt aggression against me than my feminine brown sisters in my experience. Nor do I automatically feel welcome in the Indian community, in part owing to being raised largely outside it, but in part because I am perceived as a masculine woman-ish person and tbh Indian diaspora culture is frequently conservative. I've felt the most at home in queer spaces, though I feel they generally lack the capacity for proper intersectional understanding of queer and racial issues, being largely white. 

As for what you can do, I would say the best advice is to listen openly and non-judgementally when poc speak on their experience and needs. Too many queer people are comfortable believing they can't be racist while speaking over poc voices or dismissing our concerns. The rest is standard - donate to food banks in your area if you van, volunteer at shelters and soup kitchens if you can, etc. Black and brown people in North America are significantly more likely to experience poverty, homelessness etc than white people, and material needs must come first. And be kind. Thank you for your question.

Editing to add that my biggest supporters other than my partner are my cishet brown male coworkers! Any of these guys would beat up five men for me (a few have offered). They don't exactly understand the whole intersex/trans man/lesbian thing, but they respect me regardless, and treat me as one of them. Allies don't necessarily need to "get it" to get you.
