Do you think LGBT people and allies are still oppressed underdogs, or is the victim mentality being overused?

Background for this question is a conversation on a LGBT Facebook group. The group had identified a man who had made a request that offended a lesbian woman, and the group was unified in supporting the woman and bashing the man. I voiced concern about the one-sidedness I was seeing, and in doing so I described the man as an "underdog," and the woman quickly replied and insisted that "LGBT folks are the underdog. Always."

It seemed odd to me, since this was an overwhelmingly gay-friendly facebook group and a man was being soundly thrashed for a well-intentioned if inappropriate statement. Who would you say is the underdog in that situation?
