They feel it is a requirement as Christians to do this. And, to be honest with you, I respect that.
My problem is that recently the discussion has become something beyond witnessing. It used to be that a civil discussion could be had. But no longer. Some of the drive-by postings recently are becoming difficult to distinguish from posting-while-drunk. You can picture some of them having to wipe their mouths of the foam and spittle when they are done.
And in the end, it probably turns off more of their intended audience than they would like.
I trust that when Romney is done (one way or the other) they will continue to post about mormonism. Just as they were long before Romney was a national figure.
I just hope that the expose becomes a little quieter so that folks can actually hear and follow.
