As the Quran says: "Oh, you who believe! Fasting is prescribed to you as it was prescribed to those before you, that you may learn piety and righteousness" [Quran 2:183]
As a non-religious gay I probably wasn't invited anyway. But this kind of thinking is what leads conservatives to so much repression and hate. The idea that the wants and needs of your body are something which the mind must actively fight. That the scratchy, ill-fitting wool sweater of your culture is something that you must keep on at all costs. And it leads to resentment of people who are not under such self-imposed restrictions.
There is a reason in queer culture that 'shadiness' is a bigger sin than anger. Shadiness is what happens when someone represses their true feelings. Those feelings don't go away though, they just resurface in other unexpected and non-adaptive ways.
If you ask a heroin addict what their true feelings are, the wants and needs of their bodies, it's probably just "get high".
If you ask a 16 year old kid with a porn addiction, it's probably just "get off".
There is no shortage of maladaptive desires in the world, and no shortage of ways to fulfill them. I think you can trace probably half the world's problems to one word: "addiction". The motivation system of the brain gone wrong.
I think what you're trying to point to here is the other half of the world's problems, which is effectively: "acceptance", or rather, the lack thereof. The empathetic system of the brain gone wrong.
