Prepare yourself for some nasty responses to your post, though.
You wrote: I don't think that it is bad to be a homosexual in the teaching profession, honestly it may be more helpful. There are many children out there who only hear the voices of people like you who degrade homosexuals.
My response: Why would you think that they only hear those voices, why do you think it is your duty to respond to that perception, and why would you bring up homosexuality in your classroom at all? If you care about actually teaching your topic, you'll do well to avoid/prevent any and all talk of that nature. On the rare occasion when a student refers to someone else in a derogatory fashion using sexual-orientation, I deal with it in the exact same manner as any other insult. There's no reason to even revert to the Seinfeldian, "Not that there's anything wrong with that."
