Homophobia is not a condition and anyone who claims so is in denial that they are just being ignorant. It is an opinion, and although everyone is allowed to have one of their own, this is a dated opinion that should be abolished from society. There is simply no reason to have these dark age beliefs anymore.
People are scared of things that are different or they don't understand. To be scared of some because of their sexual orientation is ridiculous. I don't agree with gay people but that doesn't make me scared of them or hate them that is why the saying exist. To each it's own.
