I believe a lot of “religious” people only consider themselves such because they want to fit in existing social groups, they don’t necessarily even read religious texts and look into their meaning. They could even pray without even realising what they are actually praying for. And I think that is always a large part of any religious group. At least, this is what I see from the most of the religious people I meet in my life.
Communism is evil and it definitely was funded and actively spread by a relatively small group of people. I do consider casualties under communism as the ones ultimately caused by zionists/bankers/khazars.
