That's not the issue, though, the issue is staunchly defending something on behalf of some other group. It's noble, but it sometimes backfires because the group itself doesn't even care that much about the thing being defended.

It reminds me of the time that I got reprimanded at work for saying I'll "wear a rainbow scarf" together with a gay coworker and friend, when the coworker didn't even see what could be offensive in the statement.
