If there are people of various "races" following/believing all religions, how can criticism of any religious belief be labelled racist?

True. The majority of Muslims are white, for example.

Race is the most miss used term ever , since all human have genetic make up for many different areas , there is no such thing as race , we all just look a bit different from each other , cultural differences are the big divide , which religion plays a big part in , but all in all its coz humans are morons

People who think that criticizing religious beliefs is somehow racist don't really understand the concept.

Well, the Jews for example are a race and a religion, they even made a word specifically about their race, antisemitism, so that people knew their race was the most important, and should be criticized the least, because they're the chosen ones. Of course, if they don't tell you they're a Jew, they just look like everyone else, and because they kept so many sex slaves and raped and pillaged and were raped and pillaged, they are pretty much like everyone else. It's just the religion thing, and you know, it's stupid. They took too many magic mushrooms a few thousand years ago, and came up with a scam for lamb.
