Thank you for saying what I didn't have the courage to say. ♥It doesn't matter what a person wants to call themselves - It's simple - If you are born with a cock between your legs then you are a male and if you are born with a pussy between your legs you are a female. Your biological assignment is what you are even if altered by surgery.
Many people would argue that a person altered by surgery is afterwards that sex but that is simply not true because the biological functions of the original sex of that person are still going to function as they always have, and thus you can never change your biological assignment.
I have absolutely no problem with trans people as long as I'm not forced to call them anything other than their biological sex. I would rather call them trans, but they're still entirely male or female depending on what they were born with, regardless of surgery and hormonal therapy. (In rare cases sometimes they're born with both - I just call them hermaphrodites normally, but when I'm being polite I call them intersex.)
