I've actually seen some really good discussions there. But when you throw a bunch of catholics, non catholics, trinitarians, non-trinitarians, pre tribbers, post tribbers, seventh day adventists, baptists, methodists, calvinists, lutherans, ect.. into one place at the same time and throw in a few dozen trolls to kick things off......your going to see a lot of crazy stuff. With so many contradictory points of view, its obvious that somebody is definitely wrong in some of the discussions there. There is no inbetween in a lot of situations. The arguments are generally just a finger pointing contest concerning who's wrong.
A civil discussion between people who disagree is a good thing, but it so often details into a mud slinging contest that I can usually only stand being there in small doses.
