Personally, my main issue with Christianity..? Is not that Christians lie. (Although I'm sure some of them do that, too. But I think most of them are sincere.) It is Christianity being such a streamlined, intolerant, evangelistic, dogmatic, narrow-minded "my way or the highway" religion! Which deeply colors how MOST Christians think! Although of course there are always a few exceptions to that, too.
If Christianity could be thoroughly accepting of other paths, and NOT try to force itself, and its dogma, on other people..? I would take no issue with it.
