The don’t mix politically when it comes to running a country. You don’t have Islamic Marxist governments. The result may be the same, but the ideologies are antithetical when it comes to how they treat religion and God ideologically.
Plus You are misreading what I said origionaly. I said Islam and Communism are very similar, both are totalitarian ideologies. But as I pointed out, there are plenty of "stans" which "mixed'=" politically.
Islam and democracy don't mix either, and are far less likely to than Islam and communism, but yet here we are, with plenty of "democratic" Islamic countries in the world.
Even Iran claims to be a democratic country.
In fact,what you don't see, is a purely Islamic country, ruled by a caliph, which is what Mohammad was the very first one of. We do however, see Islamic countries run by communist dictators, presided over by the soviet Tzar, Putin.
