This hits at the core. At the heart of this issue you come to realise as a gay person that your very existence threatens other people's notion of personhood. Homophobia is not so much a fear of gay people as it is viewing gay people as subhuman. When listening to Senator Grisanti, you see someone who has traveled to the other side and understands this. People can change. I've become so cynical that it's nice to remember that fact from time to time.
