lol Mortal Kombat was founded on gratuitous shock value. Ed Boon more or less admitted this numerous times along with his disdain for some of the mechanical choices with SF. Dat hypocrisy tho
Well,MK players are idiots most of the times rather than nice persons(of course,don't take it to your heart if you aren't an idiot),plus,there are those casual players(and even competitive ones at times) who know nothing about the other game,but they still bash it.
