You are still obsessed with the protestant Christian notion that religions are defined by "Holy Texts".
You do realise that Christianity existed before the New Testament did?
You observe that Christians "Cherry Pick" from the OT and the NT and Muslims basically ignore the Quran, but you don't get that YOUR understanding of the relationship between religion and "holy texts" is wrong, not their's?
As I said earlier, one of the weirdest things you find on social media is "atheists" insisting that Christians and Muslims be religious fundamentalists. In other words, atheists who have a purely fundamentalist (mis-)understanding of Religion.
At most, a literal interpretation of the Quran (and the Bible) only condemns anal sex between men. However:
1. Girls are publicly caned in Malaysia for kissing in public (not men and not having anal sex).
2. Men are arrested and imprisoned in Egypt for dancing together at a party on a boat (not having anal sex).
3. A boy is expelled from school in the USA for wanting to bring his boyfriend to the school prom (not wanting to have anal with his boyfriend at the school prom).
4. A B&B in the USA refuses to honour a booking made by two men (to stay in a room, not a booking to have anal sex) because it is against their "Christian Values".
If religion is based on "holy texts" as you insist, how do you explain this discrepancy?
