Well, how I saw this post was actually not that she was being treated in a derogatory manner, but rather in a preferential way, that guys would automatically let her in because they wanted to "Get some" (which is really not smart). Also, this happens to me all the time, I'm a guy, and I get kicked out of the group to make space for a girl, just because the leader is a sad guy living in his mom's basement, and has no social life, so he feels as though he is finally fulfilling that social quota of "having a girl", by letting in a girl that he, 1: doesn't actually know, and 2: will never meet.
