I don't care about your belief per se but the way you trumpet it out.
Reading posts of someone like you without background info may create a mental image of a person who sometimes comes across as either incredibly smug, or as others hinted, possibly insecure. Maybe both at the same time. I don't care about this either but it can be a bit weird to see a person being seemingly immune to reasonable criticism by claiming that they mastered "the teaching" better than anybody else did just because they know an itty bitty about their religion, and call it out like a flipped-out street preacher.
I think the problem is not so much which religion people choose but the way they "use" it. Some people put their god / messiah on a pedestal and turn whatever religion they choose into a narrative of an unattainable god which can only be satified by a life of total austerity and total surrender. That's the point I don't agree with, I don't agree with people claiming authority solely on the basis that they "mastered the teaching". If somebody "mastered" something he should be put to the test as a "master". If somebody is a beginner I think he should rather admit that he's a beginner instead of claiming the highest degrees of spiritual mastership which may come across as smug and cannot be objectively verfied.
