Alumni Associations, Breast Cancer Survivors, VFW, Boy Scouts, College fraternities etc etc... Most clubs have a certain criteria for membership because clubs try to include only people with similar interest and/or shared experiences because that is what the people who are in the club are interested in, or the whole purpose for the existence of the club to begin with. Why should they expect to get some hate for it? What is so threatening about that? Besides, saying they bring the hate on themselves because of their name or whatever is literally blaming the victim.
