I could write a scathing critique of Islam, based on my reading of the Koran, my reading of Hadith, my studies of the history of Islam, my readings of articles and speeches by Muslims, my experiences in countries with large populations of Muslims and the activities of people that say they are Muslims - and not just extremists, like members of Daesh or Al-Queda or the Taliban. Scathing. In all sincerity.
I could write a scathing critique of Christianity, based on my own experiences in various churches and with thousands of Christians whilst growing up in the Bible Belt of the USA, my reading of different translations of the Bible, the history of how the Bible was compiled and edited and mistranslated over the centuries, my readings of articles and speeches by Christians, and the activities of people that say they are Christians - and not just extremists, like members of the Ku Klux Klan or the Westboro Baptist Church or Jerry Falwell or Franklin Graham or Rick Warren. Scathing. In all sincerity.
I could write a scathing critique of other religions, based on similar criteria.
I'm an atheist. I see all of the ways religion creates misunderstanding, fuels fears, discourages thought, divides people, inspires people to hate and to act on that hate and to feel justified in acts of hate. It's my hope that humans eventually reject religion, all religion, in favor of universal moralities based on humanism, value of our environment, value of knowledge, and love of the arts and sports.
So please know where I am coming from when I say that Donald Trump is disgusting. His call for a ban on all Muslims coming to the USA is fascist, it's Hitleresque, it's un-American, and it must be condemned by anyone with any shred of sensibility - particularly Republicans and Christians in the USA - with no qualifications whatsoever.
