Some appear to be sour dours or dour sours and always go for the unfun rather than the fun. Is it because they have no sense of humor?

I have personally experienced them on Answerbag and here. They only ever show up in a fowl foul mood ready to attack insult. I conclude from that it is all they are anywhere they are. I cannot believe they save it all up for me. I'm a nobody. So sadly the dour sours must live with other dour sours else how could they stand one another? I'm gonna ask. Thank you for your reply. Of course perhaps that is all I bring out in them. Perhaps they are truly witty intelligent delightful charming entertaining with others. Perhaps that's true. Thank you for your reply R!  :)
