Yeah he did a whole debate on to a Christian Anarchist, mostly friendly but he repeating /r/atheism tier anti-God arguments. Which there are good arguments for Atheism (Which while good and thought provoking, I just can't accept the idea of Atheism since to me it just makes no fucking sense whenever I think long and hard about it) but Vaush's arguments are just shit you'd hear back in 2008 from dunning-kruger retards like Dawkins where it's a bad argument but worded to sound smart but it falls apart when you apply even basic critical thinking to it.
Skip to 28:30 in the video and Vaush unironically argues that religion leads people down "bad roads" with things like for example if a bad thing happens to you, you use that bad thing as a learning experience and he also jumbles things in like Tarot Cards and Horoscopes to make the idea that bad things happen for a reason and you can learn from them is silly. He even openly states that
"The Experts(tm) state that being religious is a flaw in the brain!" and basically implying people who are spiritual/religious are mentally ill. Which again I'd expect this argument from 2008 from some new atheist retard who thinks he's smarter than he actually is.
To be honest though, You cannot be a Christian and be a Leftist. Since Leftism at the end of the day seeks to end hierarchy and create a classless society where everyone is equal. Either through Authoritarianism as a transitional period such as with Marxism-Leninism or jumping straight into it like you would with Anarcho-Communism. Both men such as Karl Marx and Bakunin would both massive Atheists for a reason. You can't want an end to hierarchy as an endgoal while at the same time believing in God, the ultimate hierarchical figure. Doubly so if you're a fucking Anarchist. Heaven in Christianity isn't a Commune where everyone is equal. It's a Kingdom with God as the absolute monarch forever. On top of that a big part of Leftism is Materialism, the denial of the Spiritual. I'm not even Christian myself yet I know enough to know that you can't be a Leftist and be a Christian at the same time since they contradict each other massively.
