Civility is for the Civil

A reader sent me a graphic to accompany one of my aphorisms:

Civility is no virtue if a cover for cowardice.

The meme is crude, but I see little point these days in being polite to our enemies. As another of my aphorisms has it, 

Be kind, but be prepared to reply in kind.

But don't be misled by what I am about to post.  You must heed Glenn Beck's GRAVE WARNING.
