Felicitous Fenkies. Well don't hear that much of them I have to admit but I did talk with their members a few times when I was without a guild. The reason they stated they wanted to make a fenki guild was becuase of the fenki opression.
Have to admit that fenkies are fun to play but they are just like dwarves pushed rather quickly into a box of how they are supposed to act. Cat and female combination seems to have that effect I suppose.
No surprise there. Not at all, looking at the way most female Enkidukai are played. Proves that one must be very careful when doing things, as it may set a bad example. I don't know of the exact complaints you had, but FAIK Enkidukai are supposed to be RP'd similar to that, just as dwarves are.
Additionally, the race descriptions of Enkidukai and dwarves suggest this, at least to a certain degree. Dwarves a lot more explicit than Enkidukai.
If you don't like the way the races are set to be, then I fear that you can't try to fix this IC-ly, as it's an OOC issue. Therefore, there still is no justification for these guilds.
Edit:
Also, all other races also are supposed to be played a certain way. It's just that few seem to bother, especially Klyros players. IOW, I think the notion of an "oppression" is "not well founded", to keep with the excessively nice phrasing, even though it's starting to hurt.
/Edit
Also along the time of their creation I also remember several incidents where fenkies complained about even being unwanted sexually approached. Don't know how far this affected their creation but it would probably have had an effect in people joining that guild atleast.
I'm not aware of this, but I think that it was more a problem of certain playrs harassing others than anything else, i.e., OOC. I've witnessed this sort of thing before, yet I've never even thought of creating a guild in response to the OOC troublemakers (who were banned pretty quickly; GMs don't take well to that sort of thing, and rightfully so).
Add to that the pack mentallity the setting says enkies have and you could have a group.
No, you can't. Not a group of only females, anyway. No pack consists of females only, for obvious reasons. I suppose what you're saying is they are an attempt at "Anonymous Alcoholics" for players who like the model but not the background. I still think it's "not a good idea", regardless of how you look at it. Same for using the term "fenki" ingame.
But sure someone who is a member of that guild could tell more then me 
I'm not so sure, actually, but we'll likely never find out.
It's a guild system and the term "guild" is the OOC chosen term. It could just as well been a clan or an alliance or organization. PSguilds don't have to have any similarities with the limitations of RL guilds. That is pushing it in a box it was never intended to be in.
Im pretty sure that it is supposed to be at least similar to RL guilds. Definitely more than just a bunch of friends. If it weren't, it wouldn't require a name, nor display a label. Yes, it will have to be bent a bit ATM, but no, groups of friends
still just don't cut it.
