What I have noticed here are some who can not stand their point of view to be objected to. Their response is to trash the poster's integrity and more or less ignore the content of the post. There is a phrase for that behavior but it would not help the cause here.

There are many here who can take a hit and still continue on a sane and sensible approach to debate.
