Ladies don't bring Fraternity standards into this.
Don't try to say "well women's groups punish for this, male groups should also" There is no double standard here.
There is no double standard because men don't have an unwritten rule about this. We may never have had one.
If you want to ostrasize/suspend/expell your Sisters-For-Life for being human and liberated, thats all on you. But you have no call asking us to be hypocrites, judgemental, or limit someone else's Right to Free Expression. LOL
Liking sex and have more partners than the exec board . . . get expelled.
Like to party and get wild more than the exec board or the standards committee. . . get expelled.
Make money showing your body in Playboy . . . get expelled. LOL
Make money showing your or part naked body in a movie, PG R X whatever . . . get expelled.
Although I fully realize that this will differ from chapter to chapter. Where one chapter would climb on a a high horse and expell you, another more sophisticated chapter would just laugh it off.
