Yes I agree, and I surely know what you talk about when you talk about “the need to conceal a part of who you are to others for fear.”
I agree that LGBT in the US really don’t have to worry much about the stuff that Islam brings, they have enough of the negative influences of that to us more familiar religion. I fully agree, at this moment Islam inspired violence (yes Islam, not just ISIS, just like nobody can say that Romans 1:26-27 isn’t the inspiration to the Christians for having their attitude for 2000 years) is a blip in the US. But certainly not in another parts of the world.
Europe has just a little bit more to worry than the US (“and when he was attacking him he was shouting all this Muslim stuff but no one wants to hear that”) simply because the environment is not the same (much higher numbers, failed integration, new and big influx). Again, not because “all” believers of any religion are bad as single persons, but we should definitely be ready to admit that that religion still does what our most familiar one doesn’t anymore and that there are enough those who carry that view with them, consider:
There are no official executions of homosexuals in Vatican. There are still, by law, in the land of Mecca, and a lot of the countries which have “Islam” in the description of their state.
LGBT should not blindly repeat the claims of the politicians who lie about the “inherent peacefulness” of that religion, or that it’s just one single terrorist organization behind it. Even if there’s an estimate that these very politicians are “less bad” then their direct competitors. We should still somehow provide our politicians the feedback and try to correct them, especially when they lie.
