Lotta ignorance in here. Like listening to an old man wonder who is the man and who is the woman in a gay relationship...just a small-minded moron trying to fit something he doesn't understand into his antiquated world-view.

Waiting for your well-informed explanation. If you want to insult others some more, have at it... I'm patient.
I'm not even sure what you're asking for. A simple google search and an open mind will get you about 80% of what you need, which is just a basic understanding of what it even means to be transgendered. The other 20% you need to intelligently discuss this topic is compassion for what the person is going through. That's harder to come by, because even in 2015 the vast majority of people (especially the majority demographic on FBG's) out there don't actually know anyone in their personal lives who is transgender.I do. One of my best friends in college was a guy named Alex, who became a girl named Laura. Alex was a hell of an athlete, liked to drink cheap beer, and was obsessed with StarCraft2 in college. By our senior year, he felt comfortable telling us that he had always struggled with gender identity, and after years of counseling was going to transition. She's much happier now, with none of the inner demons that had plagued her for over 20 years.
I'm happy to answer any questions I can, although my knowledge is strictly what I've read and what I learned being friends with someone going through this.
Just remember--ignorance is innocent until it's been brought to your attention. Then, if you refuse to educate yourself, it becomes malicious. I don't think you meant to be insulting towards the trans community with your comments (although I think you knew it was insensitive and didn't care). I think you just honestly are in over your head with a difficult topic that doesn't fit everyone's world-view. That can change, though.
