I see what you’re getting at, but I can’t agree.
The problem here is that some xenophobic and bigoted people are hateful towards other groups. Often they will conflate and misidentify groups based on what they perceive to be shared traits.
For example, if some redneck in the US said “I hate Muslims”, you can be almost sure he’s talking about hating Arabs. He probably has no idea that Indonesia is actually the most populous Muslim country in the world, and that Arabs are a minority of Muslims. “Muslims” in this case might as well be replaced with “towel heads” with no loss in meaning.
And that’s what people rally against when they come in talking about how criticism of Islam is racist. They’re well-meaning, but stupid. They’re fighting against a real xenophobic hatred, but they’ve gone so overboard in making anything that could possibly be in any way interpreted as racist as a thought crime, and they simply try to shout down anyone who sounds even remotely like the bigots.
Islam is an ideology. It’s a set of beliefs codified in holy documents. It has a structure to it with a hierarchy of religious experts who are generally accepted to be an authority on the subject. One can analyze that ideology for its merits, and conclude that it’s poor compared to similar ideologies. There is nothing xenophobic in that statement, and judging ideologies is absolutely fair game.
You can then make judgments on individuals, cultures, and countries that try to live by this ideology. That’s simply logical. If you feel that an ideology is flawed or negative for those following it, or the people that are affected by its hegemony, it’s perfectly natural to have a negative judgement towards those who practice it.
But if you’re basically a volunteer racism cop who’s always on the beat looking for thought crimes to shout down, and you lack an ability to actually fucking analyze what it is you’re reading, “Islam is a poor belief system with a lot of negative consequences for those who practice it” sounds to you like “I HATE DEM TOWELHEADS”.
So I think you’re all well meaning, in that your reactions are a consequence of over-zealously trying to stamp out racism, but your positions lack nuance, aren’t useful, and aren’t able to adapt to actual real world issues. You, in effect, become an apologist for any of the flaws of any belief system, culture, or doctrine that you can interpret as also being the target of bigots. You deliberately stifle any real conversation we could have on the matter of Islam.
