if ur not trans plz don't tell cis ppl what to do to support us. there's plenty of critical discourse on this. and it's just not for cis folks to normalise shit on our behalf. furthermore, putting pronouns in bio the way you describe it looks a lot like performative allyship.

there are absolutely cis ppl who put their pronouns in their bio but do NOT materially support trans ppl in any way, or actually perpetuate our oppression. so to me it's no more of a demonstration of support as a bank putting a pride flag on their logo.

but hey, why should anyone listen to me: i'm just a trans person
