Gonna plaggerize you for a moment. You're words from u r post.

Criticism without content that> can< be rationally responded to, posted over and over, sometimes many times a day, degrades the board. "Poison" is a good choice of words.

This is an impossible statment, as if the poster was direct, then an answer would ensue. Attacking credibility is abstract by statement. So any reply can only be given in generalities. These statements lack sincerity IMO. I do think that you meant to say this:

Criticism without content that >cannot< be rationally responded to, posted over and over, sometimes many times a day, degrades the board. "Poison" is a good choice of words.

Here is an alludeing in general statment: The lady crossed the street with a grocery cart(?) begs to answer, what lady, when,what street,was she carrying the cart?,was she riding in the cart?, anon anon. General statements are meaningless period as the proper context can not be drawn by the reader/readers.

Correct me if you can Leif.
