When a person of color, especially if they're black like me, affirms their support for causes such as queer liberation, feminism, animal rights, or socialism, I immediately feel that I can believe, with minimal doubt, that they're truly convicted and principled in what they're advocating for.
However, when a white person claims to support leftism, until my skepticism is proven wrong, I immediately assume they're a dishonest and performative libshit. I then proceed to interact with them with hefty amounts of caution. If my assumptions are proven true, I'm never shocked.
Oh I meant as a general predictor of good politics. I'm not from the US so it may be different there but I think in the UK it's a lot easier to find an anti-racist queer person than a person of colour who's not queerphobic
