Militant lesbians would do that, however, not all lesbians hate men. They are attracted to other women and just prefer not to have sexual relations with men
On a more serious note..........
There are women who make a choice to form relationships with other women and this is their 'rationalsed' rejection of men. They would all have to give you their indvidual reasons for doing so....
There are others who see women as being as fascinating, attractive, sexy minxes as men do............
I haven't met a lesbian that hates men. Men shouldn't flatter themselves, women don't just group together in a campeign agains men, they have better things to do!
