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.
In Islam you're not hated or judged for what you call your true feelings. You are however instructed to gain mastery over those feelings and make them subordinate to you rather than the other way around. Fasting is one of the things that can help with that. As for feeling invited, honestly I get why you may think that (because a lot of Muslims do a frankly terrible job of marketing) but that's not how Islam looks at people, it doesn't look at people as unchanging monoliths, instead you are seen as a blank slate and whatever actions you do impact your life here and the life hereafter. Basically your inner reality is between you and God. Islam fully understands people have all sorts of desires, lusts, etc, the thing is in Islam you aren't cursed for having those desires, but for acting upon them rather than gaining control over them. HTH.
That sounds exactly as repressive and hateful that other major religion, as well as historical laws which punished homosexual acts in many western countries. You have highlighted the difference between our desires and our behavior, but you seem to deliberately avoid acknowledging that straight people are permitted an institution in which their desires can be met within constraints, but gay people are not.
"You're invited to participate in our faith so long as you scrupulously act like someone else for your whole life" sounds a lot like an unvitation.
You also acknowledge that even straight people have constraints in Islam, i.e. no sleeping around etc, why not also argue that it's somehow terrible that straight people have to repress their desire to fornicate?
"You're invited to participate in our faith so long as you turn your focus away from your base desires and towards God and the hereafter"
You're insinuating that you're being targeted or singled out whereas Islam "blanket-bans" entire categories of what are considered regressive behaviours such as overeating, you're not being targeted here, so can you stop with the victim complex please? Islam is as against environmental destruction, abuse of animals or overeating as much as it is against what it sees as wrongful sexual desire. What I feel like is being missed for the trees here is that the "holisticness" of Islam. It's against what it sees as destructive behavior, without prejudicing or singling out any specific group. Look at the higher purpose here.
You can accept that or not, but it's disingenuous to equate asking gays never to have sexual or romantic relationships, to asking non-gay people just to curb excess.
That's not an equal imposition, it feels like self-equivocating ad-hominem to read "you're not being targeted here, so can you stop with the victim complex please?"
If you agree that it's better for gay people to never experience intimacy, please just say so, without labelling the concern (that gay people may feel less invited) as ridiculous
Forbidding a person from lusting anyone other than spouse whether they like it or not is no different than forbidding a person from having gay desires. And no amount of self identification can label that inhumane.
