Something of which many people might not be aware is the tendency of homosexuals to go ultra-violent. They will often react all out of proportion to some offending event.
They are often real psychotics who keep their maniacal tendencies bottled up until some event releases them, and they shift to ultra bloodshed mode. They tend to be very vicious murderers, often stabbing their victims 50 times, or trying to cut off their heads and such.
Just so long as they keep the killing among their own sort of mutants, I don't see any problem. The more, the merrier.
They're already mentally ill, this doesn't surprise me at all.
