You can also be brave and not give a fuck how anybody that would think less of you for being compassionate might stigmatize you. But this is the internet and I have no context.

This seems like a non-issue, just personal anxiety.

if I defend the bi ppl ill get a stigma attached to me

By whom?

Oh fuck off with that.
