i knew it. unfortunately you are wrong.
i can explain it, however i myself am not a scholar to comment on this, so i nor anyone else can give their own thoughts about this, it has to be what islam says, not what i say. and you being a non muslim will not accept the answer as i have mentioned a few times before. so like i've said before i can prove that humans choose to be homosexual, but i can't comment on the animals as i have not studied the Quran nor the hadith and sunnah of the prophet.
Well clearly you can't prove it. If you are simply unwilling to prove it, you should not claim that you can.
I could agree that I would not accept something to be true simply because it is in a religious text - for that, I
would have to be a muslim. However, I will except that the Qur'an does not contradict itsef - if you can explain the contradiction I've pointed out. I don't need to be a muslim to do that.
So to reiterate the contradiction:
1. Animals have sex with partners of the same sex.
2. The Qur'an states that there is a natural disposition (fitrah) which Allaah has created in mankind and animals.
3. Animals have no free will, therefore they cannot choose to go against the
fitrah.
Either there is no such natural disposition (or at least, it includes homosexuality) or animals have free will. Explain the contradiction, please.
