The humor that I found disgusting is the obscene "f" word dominated banter I saw on the DUmb website that you apparently like to lurk on ... Anything negative that happens to the far-left-of-the "Karl Marx" crowd I find especially appealing as "they" seem to get away with literal murder (i.e. Mary Jo's fate when she rode in Teddy's car). Using your and Michael.SF.'s analogy, because Castro routinely executes political opponents, we shouldn't criticize his regime...hello???
I do lurk at DU... I find them to be juvenile mean little twits... I just wouldn't emulate them, I'd stand far away from anything that resembles them. But that's just me :~D
