Condescending responses - why?

Being new here I’m still trying to figure out the dynamics of this group. There are quite obviously very diverse opinions and also incredible knowledge. I enjoy the heated topics and responses as it seems most everyone here is aware and respects that we all view things from differing perspectives. My question is why are there some flutherites who feel it’s necessary to answer with complete condescension? I know that we can’t answer for anothers actions, but I’m curious to hear your collective thoughts. Joking about incorrect spelling is one thing, being rude is another. Pointing someone in another direction for answers (perhaps Google) is helpful; but if they posed the question here first, perhaps they are looking for human contact and input…why be so curt? Maybe I’m in the minority but I just don’t get a kick out of belittling someone needlessly. Patronization can be funny with your tounge in your cheek, being rude is more akin to having a pole up your ass! Go ahead – throw your patronizing responses at me; I can take it. ;) p.s. I recently responded to a question myself with a curt answer about the quality of the topic. Later upon reflecting about the exchange I realized I should have just ignored it if I found it not to be of interest to me. Or perhaps just offered my opinion more tactfully.
