I think a lot depends on the views and attitudes of the person looking at this site:
Are there are false identities, imposters posing as saints, bitter people? Of course! This is an anonymous internet forum!
But there are also many caring, loving, deeply reverent and joyful Christians on this site who love the Lord! These dominate by far!
Deep debate and passionate discussion is not needless chatter and noise. There was a deep debate and discussion about important issues in Acts 15 (just one Biblical example). But admittedly, some "good discussions" can get really hot, and we can come across as despising the other person - I have done it on this forum - and the best we can do if this happens is repent and say "I am sorry" - Our attitudes and responses are read by many people. . .
