First, you need to understand there is a difference between good Christian behavior, good forum behavior, good etiquette, good social behavior, etc.
Jesus would be banned from almost every Christian forum on the web. Jesus wouldn't make it a day on christianforums.com. So is being banned from a forum a sign of not being a Christian? No, it is not. It just isn't. Those thinking that not following forum rules is a sinful need to reread what Jesus thought of the Pharisees.
If you think that people are in agreement with how Christians are to act, you need to ask some of the pacifists here. They believe that any of you who went into the military sinned. Hey, if I wrestled the gun out of the hands of a man trying to kill a room full of children, one person here stated that I would be sinning. You need to not be vague.
Post the scriptures you're talking about. You may find that there are differing opinions on it.
Abusive how? Like praying publicly for someone to demonstrate how pious you are and how evil and wrong the other person is?
Haven't you learned recently from the leftists? Vague definitions lead to biased judgements.
What's unkind? For example, I thought that publicly questioning a family's salvation right after a funeral was "unkind". But my opinion was different from others on this forum.
I don't understand this one. Everyone knows that the people on this forum are so old and senile, we can't remember long enough to hold a grudge.
There are those who go from forum to forum to cause problems, set fires, and basically be destructive. They are poison to every forum - not just Christian ones. IMO, they should have our pity.
At other times, a person just doesn't "fit" in a forum. I would likely get banned from the CARM forum if I ever joined. I would likely get banned from RCC forums. Christian forums comprised of mostly RCC and reformed-type churches would also likely ban me. I don't see being banned from a "Christian" forum as any sign of one not acting Christ-like.
Some of the topics here are harsh and people are defending themselves against salvific condemnation from others. Anyone who comes on this forum and says they are SDA or RCC automatically announce that they believe we're headed to hell. It's part of their belief system. Even among the Baptists there are battles being fought over doctrine and some won't be happy unless they have all the marbles.
So, you do have a lot of enemies. So, you could pick a side if you wanted to. Or if you want the sides to be able to talk to one another
civilly, you can just have a set of rules to govern discussions without making judgments on what behavior is Christian.
