This is utterly stupid...

It's really hard to take your above remark seriously. Are you practicing performance art, illustrating that bigots when left to their own devices will ultimately embody the idiocy of their position?

I think his point is that bigots like himself have no self control, that upon seeing two women making out, he wants to engage in zoophilia and necrophilia. That's kind of sick and twisted that his self control is so awful that he fears the consequences of viewing two women kissing would lead him to engaging in sex acts with dogs and dead bodies.
