I personally think this is a non-issue, but it's not totally unreasonable.

In CF it's definitely advantageous to play a female character, but the overall benefit is quite small. If it were a whole lot larger you could make a case that this game caters more to women than men (if it's a safe assumption that people usually like to play same-sex characters). That could be considered OOC discrimination. Nobody has a problem with characters that discriminate against each other as long as it's clearly an IC.
