He's just signaling that he has the right beliefs about the right issues, and is therefore a modern righteous dude. Perhaps we should create a compiler that works differently for men, women, members of visible minorities, gays/straights, transgendered folks and so forth. I'm sure this would be a great advance in computer science. But, more seriously, this is actually one of the great things about exact sciences - they are objective and completely fair. A compiler or a mathematical proof or the laws of physics can't be racist or sexist. Unfortunately, we can't say the same about the social systems surrounding these sciences - a university department or a corporation, or some of the individual members of these organizations, can, of course, have bias. I don't know that the solution is injecting social justice content into technical discussions. It's probably fine to have a social track at a technical conference, where people know what they are getting into. But in the context of a technical lesson, it seems like derailing off topic.
