I suspect there are a number of factors:

First, there seem to be several kinds of posters. One kind is interested in the topic and is seriously trying to contribute with a post. They may or may not have
a/ read the entire post to which they are responding
b/ they may or may not understand what they have read
c/ they might be commenting about something about which they know nothing and thereby provoke an undesired response.
Usually when there is a conflicting opinion between two posters if this ilk, they can chalk it up to differing view points and let it go.

Another kind of poster has an inflated sense of their own wit and humor and feels compelled to share it with all Pelicans. (see the first two responses above).

I suspect there is another sort of lowlife who, as stated above feels they are entitled to proclaim themselves master of all knowledge and is willing to prove to everyone else just how much they really know.

I never used to use the "Ignore" function, but I find it keeps me from shaking my head as much.

I know it takes all kinds to make a world, but at times, I appreciate someone with a respectful attitude toward this board and their fellow Pelicans.
