Sarkeesian uses Mortal Kombat as example of a game that 'promotes violence against women' (despite being known and marketed as a brutal fighting game) so one would have to wonder if she is such a noble venture to support..
The Sarkeesian Effect is a (terrible) documentary that is critical of her, but anyway, do you have a link to her criticism of MK? To my knowledge her beef was with the sexualization of the female combatants.
I am not a fan of Sarkeesian by any means (to be honest, I just try and avoid that entire part of the internet, on both sides), but there's a difference between "noble venture" and "inciting violence or other harmful behavior".
