I know this is a common complaint in many hobbies, but political statements and being socially conscious is what art is for. Many mediums do this and the weird thing is to expect it not to happen. I'm neither agreeing with you or not agreeing with you. But, the expectation that politics stays out of art is not a realistic expectation.
Dungeons and Dragons does have social and political issues discussed in books.
Star Trek does address political and social issues.
Marvel Comics do address political and social issues.
The real question should be why you would expect it not? You have a decision to make yourself and only for yourself. Is that acceptable to you or not? Do you want to be upset or do you want to enjoy the game? Does the message resonate with you or not? It's okay if you have any answer to any of those questions. What's not okay is expecting not to have those questions asked of you by art.
