This is a genuine question, because one of the reasons I left Christianity (I was raised Christian) was that I didn’t like how they hate gay people, are pro-life, etc., and overall are pretty hypocritical. But as I got older, I realized there are Catholics who are pro-choice, aren’t homophobic, and don’t have an issue with having sex before marriage, etc., and basically are not stereotypical religious people at all. But I have to ask—how do they justify this? I mean, it must be very confusing, because if the Bible does say being gay is a sin and you are not homophobic and are pro-LGBTQ+, then you are basically saying sinning is okay, which goes against their very religion. How about Catholics who swear? Basically, how do liberal Christians/Catholics justify their religion? Why be religious if you aren’t going to go all in?
Humans have no problem holding in their mind simultaneously two fundamentally opposing ideas. Your question stems from the assumption that beliefs and especially religious ones are borne from this sort of unimpeachable internal logic, if A then B. That’s enlightenment wannabe thinking how we should be. And it isn’t like that.
Also, we are herd animals, we want to belong to something. A lot of people want to belong to this or that religious group to fulfill their own needs. Even if they disagree with some of the religious commandments. So they espouse stuff they don’t actually agree with without any or much internal conflict.
I also feel that few people are actually “raised Christians.” They tend to be raised Baptists, Presbyterians, Catholics, Mormons, etc. They have wildly differing views on that carpenter from the Middle East and what it all means.
