Sure, I agree with that, but it is nice to show the world that "non-members of group X" can stand up for group X anyway. This is still a bit of a tricky thing. See non-members sticking up for a group can imply weakness, and goes against certain empowerment based philosophies. Think how many times you've seen the equivalent of "I don't need you to fight my battles" in some "X movement" themed movie.
