Sounds like you may be justifying your conclusions instead of the other way around.
Note that I didn't state everything on my list is wrong.
I've had a lot of great conversations with religious people about the nature of their faith, but I have never gotten a good answer on why they chose their particular organized/named faith. Other religions have people who believe just as much as you do that their religion is the "right" one and all the others are wrong. How did you come to choose your particular form of Christianity over the dozens of other named faiths you could choose that have equal levels of historical correlation to their religious texts?
When various sects happen to go head to head, it’s like watching an MMA tournament where a very few competitors are well-trained in BJJ and most of the rest seem to hold a white belt in karate from the nearest strip mall. It’s usually not a competition, but a one-sided beating. Caring about some amount of intellectual seriousness would clearly narrow one’s options down a lot.
I know some who are strongly religious about their political party. I was treasurer of my local Republican party for a while, but I was able to leave them when the party it self starting going off of the things I supported them for (the local party is still pretty good). I might return in the future, we will see.
