I don't see how it changes the situation. You can never know the exact life situation of any particular individual. I may be a member of one (or many) marginalised groups. I'm aware I'm ignorant of many issues, including even those that directly concern me.

Still, TinkersW's comment amounts to "don't be gay". That's exactly the kind of thinking that enables this problem in the first place.

Whether you're privileged or not, tolerance could be as simple as just letting people live their lives. Acts of discrimination, hate, aggression - whether mandated by law, by customs, or else - these are all wilful choices, made by people who commit them.
