Religion is "a choice"; race is "an innate characteristic"; discrimination on either basis is equally unacceptable in civilized society.
Nature discriminates unapologetically. I can't have a baby though I can Father one. And two men can not have a baby no matter who pitches and catches. Natural law is a harsh mistress.
Homosexuality is a mental illness, a gross sexual perversion, a grave moral failing and so on.
Whether it’s a concious choice or not has little to do with the question. For some it is, for many it is not - at least as far as same sex attraction disorder. But every sex act by anyone is a choice. One can choose to act or not to. That’s one of the differences between being an animal and being a human being.
Discrimination because of race or religion in public or by the state is wrong, of course individuals can discriminate all they want to. But homosexuality has nothing to do with race or religion since it is a mental illness and moral flaw and such people are not only dangerous to themselves, but to others, and the sickness is also accompanied by other character flaws, such as higher rates of drug and alcohol abuse, domestic violence, crime including sex crimes, pedophilia and more.
Actually a person would be crazy not to discriminate against homosexuals.
You don’t believe that there might be rational reasons to discriminate on the basis of a choice? Even a religion that is a “choice”.
If there were a religion that mandated that all people of another religion should be killed or oppressed, wouldn’t that be an appropriate reason to discriminate against someone who embraces that religion?
One of the major problems we face is that being judgmental is somehow perceived to be “bad”. We should damn well be judgmental, else we go down the slippery slope of moral relativism.
Oh. We are already doing that.
One can also argue that pedophillia is genetic or a choice, yet we do not tollerate that. Some people even want to marry inanimate objects, some want to marry animals and anything else you can imagine.
To pretend sexual disorders are normal and not infact on par with disorders like bipolar, and major depression does a major diservice to society.
