As someone who is not homosexual nor homophobic, I could give two shits who is checking me out. If you are so uncomfortable with your own sexuality that you are afraid that one of these big mentally ill queer monsters will make you gay by looking at you? If so, maybe you need to reconsider your own orientation. If you can be changed that easily, maybe you already are gay and are looking for a reason to come out. Either that or make sure you avoid the queer lasers beams they shoot out of their eyes.
Again, provide proof that homosexuality is a mental illness and not just genetic variation such as eye color or hair color.
