But American conservatives are ignorant. Besides they are stupid.

"his/her/their"

Oooh, look at you, reshaping the language like a true social warrior.

Nothing at all to do with reshaping the language -- it is just preciseness. Until recently, I have avoided sentences like "someone said that their arse was torn up", because it is not logical: the subject, someone, is singular, while "their" is plural. Instead I have used "his/her" or "his/her/their", just like TS did.
