I can afford not to care. Sure in situations resembling servility I might have to revert to a more polite manner of speaking, but I make great effort to avoid them as they are debasing.

A lot of the folks here on HN are responsible for the current reality of tech. A nice polite discussion is great but I want to express strong feelings and make people feel bad for their choices. And politely debating the merits of something does not do that.
