Ok let me brake it down, Ether they are sexist or more likely they are a bunch of guys who know they cant control their collective pants, and Women + err "amorous" male = drama often.
yea its stupid of them but i see why they would.
iv seen guilds fall apart after ages of being like top on the realm due to X broke up with Z, Z rages, guild sides with X or Z guild splits apart
I repeat is stupid to exclude based on gender. if you are really worried about that do interview to determine the maturity of players male or female before you let them in!
also please note I'm not implying in any way that all men can not control them selves or that men are the only ones who can't, I'm just saying it happens
