Meh, just some routine lib-trolling. A non-politically correct joke, to which someone, in this case a web personality, decides they can get 5 minutes of increased fame by complaining about, knowing a bunch of liberals will flock to him without bothering to think it through as to whether there is a real issue here. We see it every day now, and the fact that people keep giving it attention and discussing it is why it continues.
There is no question that it's an attempt at a non-PC joke, whether you think it's funny or appropriate depends on your sense of humor. That said, the bottom line is that now people are talking about Adam Sessler, and that was the intent OF Adam Sessler in bringing this up. It's not like there aren't a million cracks like this made every day, in both directions (women bash dudes too), or even this being a uniquely obscene achievement due to involving a dark play on words in connection to a gaemplay event. The only think here is Adam Sessler feels the timing of this one can be used for self promotion and attention getting, so he's exploiting it. It's not like he's jumped on every other achievement that wasn't politically correct through his career, what's differant now is that as someone points out he's changed venue and probably wants attention and to make sure his name stays "out there" however he needs to do it, and a bit of faux, self-created, contreversy, attached to a major title is a way to do it.
There is no real need to justify God Of War, or Kratos' character, that should be painfully obvious, and someone who has been around gaming as long as Adam doubtlessly knows that, just as he knows he can really rev up the left leaning elements of the gaming community by pretending there is some kind of an issue.
Such are my thoughts and observations, basically your making the problem worse by discussing it to begin with.
