> I know you just said “religion,” but I can only speak about Christianity as I’m deeply familiar with it.
I believe you when you speak of the bad experiences you had, but you seem to think that what you've seen is the only (or at least the typical) manifestation of Christianity. But that isn't true, and if you do indeed believe it's true I respectfully suggest you aren't deeply familiar with Christianity the way you believe.
I am a Christian, and I was raised Christian. I have never once seen a community such as you describe. I realize they exist (everyone knows about the WBC, for instance), but they aren't the norm. Christians I have known aren't trying to indoctrinate anyone, and they are quite happy to entertain respectful discussion and debate about their faith. They are only human, of course, and like all humans they don't wish to constantly debate things they settled for themselves ages ago (so you are sometimes going to get individuals who shut you down). But on the whole Christians are perfectly willing to engage in introspection or intellectual debate to the same extent anyone else is (because let's not forget, many people don't do introspection or intellectual debate of any topic).
> It’s slowly dying in every developed country because it doesn’t make sense when logic and science are applied.
You are welcome to your opinion, but it stands at odds with the fact that there have been many Christian intellectuals throughout history. Scientists, theologians, and philosophers have all found that their faith still makes perfect sense in the context of their intellectual pursuits.
