I'm not. He has issues with the sexualized clothing and says the opposite would be dignified clothing. So sex is the origin from which he arrives at dignity.
I applied the Wikipedia definition (quoted by you) to show that he is in fact slut shaming.
If MK tells women to dress like that it tells people to kill each other. BTW, he only dislikes the sexualized clothes, not the violence.
I think he has a problem linking MK with reality. I hope he understands he shouldn't maim people. So why does he expect women to dress like that because of a game?
You make a claim, you're the one who has to prove it.
This is starting to make my head hurt;
You say that he has a problem with "sexualized clothing", "sex is the origin from which he arrives at dignity" which is weird since he never once utters the word sex or sexualised. He doesn't talk about sex at all really, he talks about objectification which is often a closely related but totally separate concept, you are the one who is conflating his comments with sex. Furthermore the context of dignity is with regards to armour and fighting he seems to consider armour an essential part of being a fighter so dignity in this context as much, if not more, about dignity in being a fighter as to in dignity in being a person. You are making a lot of assertions based on your interpretations and for someone who seems obsessed about proving a claim you sure haven't done a good job of proving you initial statement.
Theo seems more than capable of being able to separate reality from fiction so I have no idea why you are accusing him of not being able to do so. He is talking about objectification which is a pretty darn accepted thing (here is a sort of primer by The American Psychological Association, more specifically counseling psychology), it isn't that it just is Mortal Kombat, it is that there is a multitude of media telling women to behave and appear in a very specific manner.
You're obviously free to disagree with the comments put forward by an twelve year old made with the level of eloquence which that age entails. But to take his words out of context, twist them using nothing more than your own sense of logic and then use those interpretations to make some vile accusations is utterly abhorrent.
