Leftists are largely non-religious, rightists are the religious fanatics.
I know. Yet every time someone criticizes Islam on the internet, leftists jump in to accuse them of racism. I find this inconsistency weird.
Those people are defending non-extremist Muslims, not all Islam. There’s a huge difference, though I don’t expect you to grasp it based on the general level of ignorance you’ve displayed thus far.
The problem is religious fanaticism. It doesn’t matter what the flavor of your extreme fundamentalist religion, the cyanide Koolaid it represents will kill you. Don’t think for a minute that extreme fundamentalist Christians wouldn’t do similar stuff.
