I really wouldn't call the emotions 'hatred' from the persons you refer to, but rather disliking because of crappy experiences.
However, one must remember that just as there are nasty gay people, there are also wonderful gay people that are truly warm and loving personalities, however this definitely do not account for all of them, and if you would ask around here on Susan's, you would find that a lot of members do not have very nice experiences of gay people at all, but in many cases in fact far better experiences from Straight people. Oh the irony, huh.
An FTM explains a classic example of this: Transphobia in the LGB Community
Without the help of the gays and lesbians, I have no doubt that my job would be hell right now. I go to PFLAG meetings every month and I do feel extremely welcome there. And I've never had anyone who is gay, bi or lesbian tell me God hates me, You bought into Satan's lie, etc.
As a straight guy I will admit that I do look at a girl who is pretty but there had better be a lot more than a pretty face. I always looked for a true soul mate who is a caring loving girl. I am not your cave man type of of guy who is still pounding rocks together to start a fire and I truely feel that what is between your ears determines your gender and makes you a true girl. A former gf was transgender and I never viewed her as anything other than a wonderful girl, she is a loving sweet girl, and I still care for her even though we are not together. It was a matter of being at two different places in our lives that we couldn't work out that we aren't together still. So girls there are some straight guys who don't have their heads in the rear end out there who love the girl for who she truely is and the rest doesn't matter.
It worked out though. Tigger, I think found his soul mate after all. His former gf felt that, he deserved someone who didn't have the hangups and emotional baggage that she carried. Having said that, If any girl here were to date him, she would find him to be a very caring and loving man. He just needed a little education at first, given he had not known much about transsexuals in the first place.
It's that ability to look into your heart and past the exterior that I find endearing and just a small part of why he is my best friend.
