And when it comes to marginalized/stigmatized communities, I listen to the members of those communities and avail myself of whatever resources they offer. I try to boost/support them however I can.
I don't lecture a member of a marginalized group about their own experience, especially if it's a marginalization I don't share.
My general rule of thumb is that marginalized people know more than I do about the challenges they are facing, and I should support them without drowning them out.
