The BDF is great.
We are all free to express ourselves, good or bad.
It teaches humility.
We realize we need to control our words if we are to represent Jesus the way he wants us to.
We grow in our faith.
Some may go there just for the sake of an argument.
If you feel that happening, ignore them and move on.
That's the Christian thing to do.
Yes, I know, easier said than done.
But if we ever get into a debate with a non-believer outside the forum, we need to be on our best behavior, and the BDF prepares us for that.
