Athieism, or nontheism has nothing to do with this kind of religious insanity. I’m sure you could say that the religious left is just as objectionable.
I am a Christian and I do believe that.
However, even if you put “my religion” aside what we are witnessing is a complete war by Islam and the radical left against the Judeo-Christian philosophy of self-determination that formed the foundation of our government and culture.
You don’t have to be a Christian to understand this. The Christian religion and philosophy is based on freedom to believe or not believe. This sacred right of self-determination extends to everyone (our Constitution). Leftists and Islamists oppose the right of self-determination and that is a fundamental difference.
They both want to turn government into God - the left through collectivism (all rights come from government) and the Islamists who want Shariah law and an Islamic state that severely punishes those who don’t comply. While they are miles apart culturally/socially their hatred of self-determination links them in an unlikely alliance against the basis of our constitution.
