This subject seems pretty cut and dry to me, you are one biological sex or the other based on genetics. I made the drunken mistake over the weekend to voice my opinion on this subject in another forum that happened to have some old He-She "tranny" on it (66 years old!). I said that sex is biological and everything else is mutilation (as in surgical transition to another "sex").
This tranny, who was not even posting yet, started straight up with the insults and try to characterize me as using low IQ Neanderthal thinking, incapable of real "debate". I ended up telling this guy I have my opinion and wouldn't bite. Well, since I wasn't playing, he continued on and hijacked the thread. He made it a soapbox to tell everyone his life story basically, not what the subject of the thread was at all.
I considered posting your info, but I know this guy would get out his tranny play book and start quoting from it. Like I told him before I signed off, someone like him is so condescending that they would never consider any other opinions. So I just told him I believe what I believe and refused to debate it. It can be so hard to not feed these trolls, it gets to the point where I second guess my posts and self censor and I hate that. I but don't want to contribute to some insane discussion that hijacks a thread, it a total waste of my time and it just gets me more pissed off.
