It's so difficult. Generally, with a few exceptions (trashing the scriptures/heavy textual criticism, ongoing contentious free will/all sov and Trinity debates) we really try to not moderate or edit people's beliefs, thoughts, questions...people can believe how they see things, or not believe at all. If we chased away everyone that didn't agree with us, at some point, what would we be accomplishing? Seems to me this is a very good place for ET'ers or atheists to come...aren't we supposed to interact with them, love them, share the gospel with them? Same thing with varying beliefs. I'll "bet" there's not any 2 people on these boards that see everything absolutely 100% the same. And IMO, that's OK - IF, WE TREAT EACH OTHER WITH RESPECT, DON'T TAKE OBVIOUS OR VEILED SHOTS AT EACH OTHER (which is baiting, flaming, calling out others beliefs as stupid, ridiculous, etc [outlined in the FAQ section] which are all warnable/bannable offenses).
Some absolutely won't abide by the forum guidelines, or respond to ongoing attempts to help them be able to do so, so unfortunately, in a community like this some will be banned. That doesn't mean they're not loved, concerned about, prayed for...but if someone just continues to stir up dissension, cause strife, criticize others, embarrass others - all things against the clearly stated Forum Guidelines, then at some point the limit is reached and they may be banned.
So, there's still room for MANY varying opinions, understanding, interpretations, beliefs...there are just ways those all need to be presented. And the main thing I believe we often get away from is, POST 'AS I UNDERSTAND', 'IN MY OPINION'!!! Then things can be discussed, considered, and then either learned from or respectfully dismissed. No one choking the other into submission OVER PERSONAL UNDERSTANDINGS of things that are otherwise not outside the forum guidelines.
