I'm starting to think there ought to be some kind of "no spamming" or "no derailing"rule...
Naturally, sometimes, one sentence replies are appropriate..even one word replies occasionally...but when people consistently, purposely try to derail a conversation or pretend confusion in order to sidetrack a discussion, there should be a procedure to deal with that....
It's a judgment call and up to the moderators..who are appointed by some random procedure according to who is friends with whom.....and THAT'S another issue, but there are too many agitators now that are skirting the rules just to be inflammatory and serve their egos and "needyness".
