I've had my fair share of both obnoxious men and obnoxious women. Granted, more often it was men, because the majority of people with headsets that play the games that I play were guys, I've encountered both nonetheless. You will run into horrible people everywhere. It's a cruel world. An all women group will still have problems, even if those problems are of a different nature. Go ahead and make an all women group, but I think a person like you who has been victim of harassment is better off creating or joining a small and personal group consisting of only respectable people.
