Far from it; the bald, white space-marine is one of the most over-used characters in modern gaming. But it increasingly rare that they are lone heroes. A shift towards team-based, co-op featured games is undeniable. In this way, mainstream video games, even those seemingly void of political statement, are implicitly political.
No, they're not "political". You can interpret Mozart's Fifth to be racist, but that doesn't mean he wrote it that way. If you keep looking for racism everywhere, you are racist: everyone else doesn't think about it all the time.
I believe you're the mistaken one. As adequately put by Virginie Despentes in her book King Kong Theorie, some ideas are so ingrained in our own culture that we end up failing to even see them in action.
The most interesting part is that you accept those ideas even if they are detrimental to yourself just because "it's the way things go".
You can also think about The Matrix, ie. when you're part of a system you easily become blind to its limitations and can even come to defend them (becoming an agent).
To get back to your point, what i mean is it would be ok to acknowledge an portrayed idea, or some kind of interpretation of a piece, but not adhere to it.
On the contrary, dismissing the idea as non existent or something like that does not reflect a better or more elaborate point of view.
More simply put, not seeing is bad, seeing but not caring is somewhat better.
