I've said your description sounds "exactly as repressive and hateful" as another major religion and the laws of many western states until relatively recently. You're insinuating that Islam is being targeted or singled out whereas I will blanket label as homophobic any regime which masquerades as being even-handed because they generously permit queer people to pretend to be straight, so can you stop with the victim complex please?
Liberal humanism is against what it sees as destructive and oppressive behavior, without prejudicing or singling out any specific group. Look at the higher purpose here.
