How many bitter Jellies do you suppose Fluther has?

I hope it is just something I notice, but not really. It seem to me that some Jellies seem bitter, and unhappy, not many, but some. No matter what thread I see them in, they do not have much good to say, either about the issue, or an answer some other Jelly made on the issue. I wonder if this caustic attitude is the catalyst on certain threads where spats erupt; to the point, the mods redacted many comments once I return. If the thread is one of iron and not fluff, spats seem to break out anyhow, but someone who goes in bitter, to me, has more of a chance of causing one. I use the construct that whomever I am engaging is the banker I need to get the loan from to save the family farm, so even if I disagree, I will shoot for being as respectful, and civil as possible; even if I am having a crap day. Do some people have a crap day all of the time that they appear to be bitter, and caustic, or is it them and they are not aware?
