I can't stand straight people anymore.
Why do you feel that way about straight people?
I don't know, I just can't handle these kinds of people.
You shouldn't make judgements about someone based on their sexual orientation because that's only a small part of who they are. You should judge people based on their personality and their actions, not based on who they are attracted to.
They all think and act the same way.
I don't think you like it when straight people discriminate against other sexual orientations, yet you are doing the same thing to them. If you want people to be tolerant of others you should start acting that way yourself.
