> This insistence on political correctness

It isn't "political correctness" - the phrase implies that the language has no real effect and changing it is merely for show, or as a political statement.

Using male pronouns as gender neutral has a measurable effect on comprehension that has studied and reproduced repeatedly. Using "he" pronouns as generics does in fact lead both men and women to exclude women in their comprehension of the sentence a statistically significant fraction of the time. See for example http://www.jstor.org/discover/10.2307/27784423?uid=2&uid=4&s....

Revising language not a "thought barrier", it's an actual real benefit.

Your entire premise is false.
