I am also jumping to the conclusion that there was some level of deciet/confusion surrounding the shemale's posessing of a Y chromosome.
I am a liberal which means "do you". Pretend to be a woman or a Vulcan if you want. What's NOT cool is fronting like you ACTUALLY have XX chromosomes. Like you get a period. Like you want to get pregnant some day. That shyt is downright terrifying to me as the tech gets better and better.
I would never kill or even try to severely injure a tranny if I fell for the okey doke. Perhaps a spirited round of fisticuffs but not the psycho kind. Just the old fashioned - bust a lip, black eye - routine.
