"Political"?

I think it may have been a few decades ago, when the pronouns were invented, but at this point Spivak is generally used for courtesy purposes, as Alicorn said.

Breaking the flow I'll agree is a valid objection, however. I have opted to avoid neologistic pronouns for that reason, save in cases where such are requested. If someone wants to be a "xe", that's their business, I say.
