Why am I being cancelled on gay groups for being anti-Islam?

I've recently been banned from another gay group for expressing my opinion that "Muslim pride", as in a gay pride for muslims (yeah, that's a thing now) is the stupidest thing I've ever heard. I mean, the reasons are obvious to me and, I would hope, for any thinking person, but that's not what I want to talk about here.

What bothered me the most is the total refusal of having a discussion. Of course, I was branded far right and islamophobe and racist, which couldn't be farther than the truth. I actually lived in a muslim country for a couple of years, but somehow I automatically didn't know anything about muslims and hated them all. Apparently the death penalty for homosexuality in almost all muslim countries doesn't prove anything, only "some" muslims are homophobic and that's because they don't interpret the Quran as they should.

It is actually scary how much in denial these people are. And it's so painful for me, as I feel rejected by one of the communities I feel for the most, just because they are brainwashed into thinking islam is benign. And also the way they do this, without any right of me explaining my position, contradicts all their holier then thou attitude.

Also, the sheer irrationality of it all. If it came from a general leftist subreddit, I would have understood. But it comes from people whom Islam targets directly and whom Islam wants dead. How can these people defend their oppressors like that? After all the gay men who sacrificed to fight against Christianity for the advancement of LGBT rights, now today's gay people chose to shit on their work. Why?? I just can't understand. It's breaking my heart to see how another abrahamic religion is winning again. For me, there is very little distinction between Christianity and Islam, maybe that the first one has been tamed a bit.

I know there are many atheists who are homophobic, but being gay on an atheist group does not compare with being anti-islam on a gay group. Mind you, not anti-christian, you can make fun of god and jesus all you like, but if you say anything against pedo Mo, you get instantly banned.

I guess I'm writing this in order to get validation from you guys, but maybe it is something I am doing wrong? Is it something I don't get? I mean, I am open to valid criticism, except I don't get that on gay groups, I get automatically insulted and banned.
