My existence is not political. If someone doesn't think I should have rights and/or exist and/or thinks I am inferior because of who I am, then no, we cannot write quality software together.

If someone disagrees with me on tax, foreign relations, government services, defense, etc policy, sure, we can disagree and still work together.

What gives rise to people like Lunduke is not a simple thing, and something I don't think society fully understands.

In a way, "someone doesn't think I should have rights and/or exist and/or thinks I am inferior because of who I am" is pretty much the definition of (some kind of) politics. All sides play this game, e.g. many extremists these days argue that the "intolerant" shouldn't have rights or even exist by definition, but then the political football becomes who gets labeled as "intolerant" to begin with.

(And maybe it's true that those on opposite sides cannot work together on good software, but that's easily addressed since all FLOSS licenses include the right to fork and merge changes.)
