Just reposting this excellent point from lemmygrad
Eh, I know it’s a minority position on the left but that’s why it’s a drum I beat every time it comes up. Unironically forced me back into religion when I realized that leftist politics without axiomatic moral grounding results in disaster.
Now I go to leftist meetings to avoid being useless and Quaker meeting to avoid being terrible.
I don’t know, if the marxists or anarchists I work with irl ever said that kind of shit, I wouldn’t work with them anymore (and we have discussed the topic). Simple as a that. Personally, I’m an atheist and haven’t come up against any contradictions between my leftism and my morality or humanism. But if religion is what it takes for people to recognize that killing kids because of some hypothetical future scenario is wrong and will never be justified, then I say keep the churches full.
