Sure the church can be this way (you can’t go in and scream the f word around young ears during a sermon or after it), but the church is just like capitalism in that you are free to join and leave any one you please (unless you have a corrupt one). I think you generalize the church too much. I come from a family that has been in different churches with entirely different mindsets, and both of my parents were raised in different cults. Matter of fact, my father was in a church where the pastor shut his church down because he realized his preaching was unBiblical. My mother grew up in one cult and joined another when she grew up. One church they were in when I was born, for example, was dealing with a mass exodus (and these people, being a part of the prosperity gospel, were financially greedy [which, by the way, is a life path Jesus spoke out against]) so they created a covenant to keep people in the church. Note that this church does not describe all churches. The church I am in now has a covenant, but it is not meant to bind you to keep going to the church for life, or anything like that at all. And the church i used to go to had a mass exodus, and they didn’t do this because they weren’t greedy like that.
What I am saying is this:
1) not all churches are the same. If one church bonds with the mafia, it doesn’t make all churches mafia members. There is actually a church in Florida that rejoices over disasters like Irma, Covid, etc. I don’t know what Bible they’re reading, because there’s nothing in the Bible that suggests this behavior and many Christians want nothing to do with such beliefs.
2) The worst thing that can happen in a church is you leaving it and finding another one. The things communists, Nazis, and the left have done for holding unpopular opinions include firing people from jobs, ruining people’s careers, and harassing people. The communists and Nazis threatened lives for disagreement. The left is not capable of that now, but if they want to shut you up and affect your life for the worse just for simply not agreeing with them, people like that end up silencing those who oppose them in vicious ways.
