In that particular game though the designer chose to make the gameplay that way for a particular reason. He particular designed the gameplay that way because he didn't want to portray aggression in a positive light, and instead wanted to portray defensive action as a virtue. Isn't that a political statement that the designer was making?
Likewise, I think there is a statement (not necessarily an agenda) being made whenever a heterosexual couple is portrayed. When heterosexuals are portrayed in a positive light, that reflects what how the developers feel about heterosexual romance. I'm not saying Square went into this with a purpose of WE MUST CONVERT THE HETEROPHOBIC or anything else, but the way they design the story is reflective of their views. Just happens to be a view that basically nobody disagrees with.
To use another example, a commercial in the US was deemed "controversial" because it featured two dads. It doesn't make a big deal out of it, just two dads getting their kids to eat Cheerios. Is this a "pro-homosexual" agenda? If so, why wouldn't a commercial with a heterosexual couple, be "pro-heterosexual" agenda?
There's a joke that I'm probably not telling right. Two fish are in the water. One of them says "how's the water today"? The other says, "What the fuck is water?"
In the same way, we are surrounded by political messages in pretty much any story telling medium. What is portrayed as positive or negative reflects the developer's positions. But when the message is one that is universally accepted and not questioned, we tend not to question it. It's only when the particular political message is one people disagree with that it gets noticed.
Certainly, you can see political messaging in everything if you analyze every detail. And yes, people at large don't perceive something as political when it falls in line with how the vast majority of the world works. Your approach to this topic differs from mine, but we both arrive pretty much at the same conclusion. I say that video games are largely free of political messages, you say there are political messages in virtually everything, but the majority of those messages don't create an issue because people don't perceive them as an attempt to make a political statement or send a political message. This point of discussion is very much narrowed down to semantics.
My original response to you pointed out that the strong negative reactions towards TloU2 aren't solely due to political messaging, but also because Naughty Dog went as far as killing off main characters for good (Ellie still unconfirmed), so the anger isn't overwhelmingly driven by people with phobiae. I think we agree on most things, if not all of them, and I am not one to sort out all semantics and argue over them for pages.
