And all of that is very valid and I would have to be incredibly thick to believe otherwise, I just didn't want people to be throwing around words that they don't actually know the definition of or people using incorrect information to defend themselves from labels.
Of course, with the problem posed above, you can also easily apply the term chemophobe to anyone who doesn't give unequivocal support to the use of artificial substances and so on.
I do agree though that we are a society built on roles and labels. That's why gay rights are still trucking, and ironically enough, I suppose you could claim something of a parallel between gay people and homophobes: What constitutes one? What are the (inherent) behaviors of one? Is this the correct term for such people? What do these words mean or imply? Should these people be treated fairly or differently? Not a perfect parallel, but what is?
That's very well, and the parallel between the label homosexual and homophobe is great. Chemophobe isn't a buzzword like homophobe. You may compare them etymologically but there are more angles to look at the issue toward. Socially people aren't going to go, "Ah yes, there's a homophobe, just like people who are opposed to artificial chemicals are chemophobes". There's going to go, "Ah yes, there's a homophobe, just like an Anti-Semitic, or an Islamophobe."
So let me pose a question:
There is a Muslim who favors Islam because that is the religion they belong to. They don't like Christianity but they haven't taken any action to interfere with Christian activities and worship. Are they Christophobic because they don't agree with Christianity by principle, and prefer Islam instead?
Are then, all people of religion,
phobic of other religions because they believe their own religion is right and the other religions are wrong, and they would spread their message and disagree with other people?
There is a Christian who favors Christianity over Islam, because that is their religion. They don't interfere with Muslims or Muslim places of worship (this particular Christian has no problem with the Ground Zero Mosque) but they still don't really agree with Islam. They have an aversion to Islam.
What grounds would you have to call them Islamophobic? Just because they dislike Islam? Does that dislike make them -phobic? There are more conditions someone has to satisfy to be Islamophobic than just being averted to it.
So what grounds would you have to call someone homophobic, if they disagreed with homosexuality? Wouldn't you have to identify some basis of fear or antipathy before you could call them phobic? What if they just don't have any (because they don't really take the issue that personally) and stubbornly still doesn't agree with homosexuality?
Not all disagreement has hatred, prejudice, or antipathy behind it; you can be against something by principle. So which is it? Does homophobia mean hatred and fear toward gay people, or does it ALL aversion toward gay people, including informed, rational disagreement? Most other forms of phobia include by rule have to include some sort of irrationality and many people assume homophobia does too. When you start including informed, rational disagreement in the definition, it sets a social precedent that hasn't been made yet. After all, there are many things that people in the world cannot agree on, and we haven't yet put -phobic suffixes on all of them. It would be kind of redundant to do so.
