1. It’s unbiblical: That may or may not be true – there are lots of people who argue that the bible is at least inconsistent on this issue, and that Jesus wasn’t much bothered. I don’t care. I’m not a Christian, and Christianity is not state religion, and I don’t care what the bible says. If you follow the bible, that’s your choice. But you can’t selectively turn biblical bits into secular law.
2. If we let the gays do their thing, we also need to let rapists and pedophiles do their thing: Err, no. Come on, use your brain: There’s a substantial difference between a situation of consenting adults and a situation where one is the aggressor and the other is the victim. If you don’t understand those basic concepts, you shouldn’t be out and about here in cyberspace.
3. If we let gays do their thing, MANKIND WILL DIE OUT: Nope. You can’t catch the gay. You are the best example for that: you foam at the mouth rather than get all hot and bothered in a nice way when you think about two guys kissing, right? See. There’ll always be a gay minority. It’s a minority. Look up the concept of the bell curve. And bear in mind: gay people have reproductive organs. Many use them.
4. Even animals have more common sense and won’t do this: Not true. Plenty of evidence from wildlife that they do do it. And gaily so.
5. But you can’t compare humans to animals: I didn’t – you started that line of argument.
6. It’s unAfrican: Me, I don’t know. I’m not African. I think all the African gay men and women might have a thing or five to say about this. And they can perfectly well speak for themselves.
7. What if the children see it? Yeah, then what? Nothing.
8. Anal sex is wrong – the anus wasn’t made for this: If you think anal sex is wrong, then don’t have it. Not all gay people have anal sex, and there are plenty of straight guys (and women) who get all bright eyed and bushy tailed about it.
9. It’s a lifestyle choice: Hardly (never mind that if I chose it, what difference would it make?). The foam-at-the-mouth hysteria in Uganda, ‘corrective rape’ and other such charitable, love-your-neighbour activities are the best example. It’s extremely unlikely that anyone would choose that kind of hatred and threat of violence just for kicks.
10. I have no issues with gay people as long as they don't chat me up - then I'll hit them: Easy, my friend. If that happens, be civilised and say 'thanks, no, but thanks'. If I hit everyone who chatted me up and who I'm not interested in, there'd be lots of black eyes, and I'm not Marilyn Monroe by any stretch of imagination. I say 'thanksbutnothanks'. To all those good Christian married guys, too.
11. Gay guys are sick, but lesbians are kinda cool: You're not talking about lesbians, you're talking about two straight women getting it on with each other for the sake of a straight man. As with the vast majority of couples, two lesbians won't be very keen on having you drool away when they get it on with each other. Pretty much like you won't slap your best buddy on the shoulder and ask whether you can watch while he's doing his wife.
EDITED TO ADD:
12. I don't understand it/I find it disgusting: That may well be the case, and you're of course entitled to think so, but that's irrelevant. I don't understand how people can spend every Saturday watching football, and I may find people chewing with their mouth open disgusting. My problem to deal with.
13. ... but don't rub it in our faces/force it down our throats: Most people actually don't - as one gay Nigerian blogger said, she never wanted to talk about her sex and love live in public because she thought it was private. But since so many other people were talking about her private sex and love life, she decided to speak out. Also: It's perfectly ok for a heterosexual man to post a picture of his wife with, say, a mention that he thinks his wife is cute. Normal behavior, right? The equivalent from a gay man, however, is suddenly 'rubbing it in our faces'.
More importantly, perhaps, the legal situation in Uganda now longer allows the option of 'as long as they do whatever they do behind closed doors, we'll all be fine'. Because even what people do behind closed doors is no longer legal, and can land them in prison for many years.
14. But they are recruiting people! This argument is, funnily enough, usually brought up by people with the most vociferous disgust of homosexuality. So you're so incredibly disgusted and repulsed - but you argue that not-gay people can be 'recruited'?
EDITED TO ADD (7 July 2015):
I will NOT publish any comments that make the same dumb statements that I have already refuted above('But we will all die out!', 'Can I now marry my dog?'). So save yourself the energy.
