Should all previous content be rewritten on the internet to be PC? This is from 2012, and as far as I've noticed, this gender neutral thingy started coming up a few years after that.
In 2012, this was already well-known. The language is jarring and sexist for no apparent reason. It is not undue revisionism.
Any level of revisionism is undue.
The point of not using gendered language is to compensate for discrimination, not to hide problems.
