Okay, I'm usually on the same page as you on these issues, Jim, but after watching this video, I have to ask the question: What the fuck are you talking about? Setting aside the issue of (in my opinion) Nintendo not saying what you implied that they said, how can you reasonably claim that including something that is a current social hot topic is not a socially political comment while excluding the same automatically is? Whether positive or negative, publicly taking a stance on gay marriage at this time(and especially in Japan where there is no clear majority of support for it) is absolutely making a political comment, as there is a lot of politics involved in the issue right now(as you yourself mentioned later in the video).
Actively taking a stance on pro-blacks or pro-women's rights isn't a political issue because the laws involving those topics are well established and long standing, so taking a negative stance on that is only bigoted, not politically controversial. The laws involving gay marriage are currently in flux, so taking a negative or positive stance on that is political(though being negative is no less bigoted).
On the other hand, I also don't believe that one is making a socially political comment either by including or excluding unless one intends to. Not everyone cares about social politics, and despite what some of the more abrasive members of out community might claim, you don't fall into the "against" column by default if you don't proudly proclaim that you are "for." You aren't part of the problem simply by not actively trying to be part of the solution. The only way to be part of the problem is by actively campaigning against gay marriage.
And that isn't what's going on here. Nintendo is a Japanese company. There is no gay marriage in Japan, no laws concerning property distribution for gay couples, and no great majority of Japanese citizens campaigning for a change in that regard. When a company from such a background says that they had no intentions of making socially political commentary through their games, I believe them, and I can't see any way to claim otherwise without coming off as a demagogue.
It's important to remember that there is a difference between you inferring something and them implying it. Intent matters, and trying to put words into someone's mouth to further your own political agenda is a bad, bad thing regardless of how benign the agenda itself is. It's the difference between your usual episodes, which are pointed commentary calling out the bullshit that people in the industry try to get away with, and this one, which comes off like a feminazi's blog reading rape intent in every word a man says or writes.
Remember: just because you are offended does not mean that they were offensive.
