And what homophobic reasons have you actually seen on the thread?
I've been on it since page 1 or 2 and I haven't seen any homophobic or biphobic reasons why women don't want want to date bisexual men.
No one, as far as I'm aware, has said that homosexuals or bisexuals are dreadful people that they avoid in all aspects of life. That would be homo/biphobia.
Plenty have said they are not attracted to men who are attracted to men and simply don't want to date men who also may have or want to date men - not homophobic.
Some have said they do not like the idea of having sex with a man who has had anal sex( with a man or woman) and do not want to have anal sex themselves - not homophobic.
Plenty have said they only want to date heterosexual men full stop - not homophobic.
All have said that they couldn't care about other people doing whatever they want with whoever they want, but when it comes to who they personally want to date and have sexual relations with, they find certain practices and types of people extremely unattractive, so would not date them. That certainly isn't homophobic, on the contrary, it's called setting boundaries, having standards and being discerning. Surely that's the ideal for choosing a sexual partner, not feeling you have to have sex with anyone that asks so as not to appear a bigot.
