No one has ever really given me a proper argument as to why homosexuality is wrong. That's why I ask for one now. Please. Tell me.

The following are just uninformed, bigoted ramblings which hardly qualify as arguments:

• Religious reasons (Keep your fairytales to yourself, the vast majority don't give a rat's ass what they say.)
• It's not natural (It occurs within other species too, and as far as I know, the straight monkeys don't go around throwing their shit at the gay monkeys, unlike their human brethren. Besides, if you're going to be really anal about it, most things us humans do these days are by definition not natural.)
• It's not healthy (The prevalence of diseases like AIDS is due to a lack of information. In the case of gay men, only a minority are informed that while the chances of getting pregnant are pretty low, a condom would still drastically decrease the chance of contracting STDs. Heterosexual couples are much more like to use prevention, and thus they have fewer cases of things like AIDS. Anal sex has its cons, but then again, it's not like homosexuals are the only ones to practice it. Beyond that, there's absolutely nothing unhealthy about being gay, unless you count the amount of abuse some gets thrown at them.)
• They don't have to (True that. If you get to choose between an apple and an orange, while you love apples and detest oranges, you can still force yourself to choose the orange and eat it. Doesn't mean you like it. Likewise, homosexuals who are in heterosexual relationships are simply pretending, to satisfy the anal world that they live in. Homosexuals who have been "cured" have a nasty tendency of becoming depressed and often even killing themselves, due to the sheer pressure society puts on them.)
• Fags are [insert bogus here] ("Fags" are sexually and/or romantically attracted to the same sex. The differences end there. They're not a different species. They're just like you, except for one minor difference that should hardly matter to you unless you're a stalker who likes watching people having sex.)

Are there any more valid arguments out there? Or, is a lot homophobia simply based on the fact that it squicks you out?
