When it's women causing drama let's remove the offending women. Sounds about right.
When it's men causing drama, let's remove women because they were making it hard for the men to think straight, thus causing drama.
I'm in no way saying there is NEVER woman-related drama (I've been in a situation where someone brought their GF to the guild and it got rather ugly... and that would've been avoided if that said GF had not been a part of the guild) but most of the time it's HUMAN drama, where the human in question happens to be a woman. People are just more inclined to think that's woman drama because "girls always cause drama"
In my current guild the people who bitch most about not getting the gear they want are men. I have passed on tier tokens for them because I'm friends with our RL and I know he's the one who has to hear bitching. If those people would be women there would be shouts of "ALL WOMEN WANT GEAR WITH NO EFFORT OMG LOOT HOES" but because they're men people are just "oh well those people must be pain in the ass to deal with" and not "ALL MEN ARE LOOTWHORES"
If you want dramafree guild, do your research. Contact their previous guild and ask them why they left if you think there might be drama involved. Check how many guilds they've been in for the past year or so. Think about how mature they are (generally people aged 22+ are a bit more mature, buuuut I wouldn't count on age only; you can have really fun and intelligent 16-year-old boys and utterly immature and petty 30+ men) and drop the YEAH HE'S MAN SO NO DRAMAZ and NOPES LADY PERSON DRAMA INCOMING thinking.
