No, the "C community" and creators aren't making a political stance on things at all. Lua doesn't either. The Zig creator is very outspoken on political matters.
Not making a political stance is implicitly embracing the status quo. That’s usually fine because most hot political issues are far away from programming language design and implementation. Others feel differently, that political issues which affect community members (or people who could become community members) are important to speak out on. Regardless, every community takes political stances, some are just more upfront about it
Andrew Kelley is just one guy and he’s allowed to express his own political opinions online, just as you are. What evidence is there that the community as a whole is “annoyingly political”?
