So, what you are saying is that I can call myself [insert religion] and do whatever I want, regardless if it goes completely against the holy texts of that religion.
There is no irony, in my comments, when a bunch of cherry pickers are wanting to force their religion on me. That survey from about 2013 showed that British muslims are against homosexuality and want sharia law, while claiming welfare for their 5 wives which is clearly against the quran. They do many things that violate the quran, but that's ok to them.
As for the atheist vs christian thing, it's because christians cherry pick from both the OT and NT, while saying that the OT doesn't apply to them. It can't be both. Either the OT applies or it doesn't. If it doesn't apply then they need to shut up about it.
Just because gay muslims do something, does not mean that it's allowed according to their holy texts. This applies to any muslim.
There are religious and cultural jews, for example. The same could be said for muslims (and others). If they are "cultural", then they have no claim on religious beliefs and need to keep their mouths shut about what their holy texts say.
BTW, I'm not sure if you see it, but your stance justifies burning holy texts because they don't matter to religion. It's extremely ironic, but totally expected, that atheists read holy texts but believers don't.
