It's obvious that Zeitgeist is a latent homosexual. He hates and fears homosexuality because deep down, he is afraid that he is gay, and he cannot accept that part of himself, he hates that part of himself. Rather than confront it, he projects his hatred outward, which helps him focus on "others" and take his mind off himself.
This explains his blind, unreasoning hatred toward a lifestyle that does not harm him in any way or even threaten to interfere with his life. All homophobes are the same, Zeitgeist. I find you pitiable and boring, but not nearly worth contempt.
