Seriously? I reflexively think about specific, often negative, things when I read about a lot of topics. That doesn't mean those thoughts have to be shared.

Seriously? I reflexively think about specific, often negative, things when I read about a lot of topics. That doesn't mean those thoughts have to be shared. I think a good rough guideline is trying to only comment if that comment has a chance of advancing the discussion, answer somebody's questions, or asks for more information. Restating repeatedly made comments doesn't do that.
