Because full KIA censors the fuck out of discussions about the tranny problem and half KIA bans it completely. The TERF invasion of TIA and SJIA after the GC purge was the beginning of the end for those subs. I initially thought that the radfems would move to the KIA subs next but after thinking about it more I don't think those subs would be very attractive to them. They can't bitch about male perverts in drag accessing their special privileges and their "muh misogyny" bullshit would get them laughed off the subs, especially full KIA.
