Anyway, don't take this the wrong way, Mae. You don't have to explain yourself, but you also shouldn't call people out in theoretical situations.
FCC has no official alliances, except to ourselves and experience. We try to merc for those who have done us favors in the past and those fighting our numerous enemies. But, I have merced for my enemies when the other side won't accept me, which is usually just after I've retired, or when one side has no idea what they're doing.
