Sexist language

After a few years as Chairman of the Applied Math Dept. at U of Waterloo, they changed the name to "Chairperson". That was a good idea. Now, the "powers that be" were thinking of changing the words of the Canadian National Anthem. It now includes the phrase In all thy sons command. That's sexist, right? How about In all thy sons and daughters command? And while were at it, we should consider these changes: Fatherland to PersonLand Mankind to Personkind. Manpower to Personpower Freshman to Freshperson Statesman to Statesperson Human to Huperson and maybe manual to man-amd-woman-ual. And how about mail? It even sounds sexist, right? I understand, too, that referring to the great painters of the past as Old Masters is sexist. When Canada went metric, I assumed that mileage would change to ... uh ... kilometre-age. Fortunately (for me, at least), we still talk of "mileage". I guess I'm just too old for this newSpeak.
