I thought "hir" was only for hermaphrodites. In general I say he/she or "he or she", but that becomes cumbersome when I have to say it frequently, and it's grammatically incorrect to say "they" when referring to one person. It was suggested once to just use one pronoun, and then switch it out for the other occasionally throughout the passage, but that strikes me as odd.
Also, I thought the original meaning of "gay" was "happy" and that it didn't become a term for homosexual until later. Either that or that one line in the Flintstones theme song always had that double entendre.
The main reason I don't like political correctness is because it means I have to learn about the new "correct" terms to call people. I don't know what to call black people, I usually say African-American. I don't know the difference between Hispanic and Latino (I know you don't say Mexicans though. Normally I'd say "you don't identify people by the state they live in", in that you don't usually hear of Washingtonians, but that would extend to countries and we certainly hear of "Germans" and "Russians" and... maybe Norwegians... but I guess those too might be incorrect, just say "people from Germany" or "people from Russia". I think Mexico's also known as Latin-America, so I think I side with the term Latin-Americans... I'll just say Latino. Maybe Hispanic would be for those that live in Spain). And I'm too lazy to go onto a website to learn the correct terms, partly because I feel the situations where I do need to know this stuff are rare.
What it comes down to is, I don't want to learn new words to demonstrate I'm using words without the intent to harm or categorize someone. I'm not excluding anyone on purpose by saying only "he" or "she", for instance.
And for the record, I say Native Americans instead of Indians. This despite my favorite elementary school book, "The Trumpet of the Swan", still has Sam Beaver walking like an "Indian" which strikes me as stereotypical today. But you know, yeah, past literature/movies/whatever get a free pass on this PC thing. They get to say whatever old now-racist terms they want, you might get a little disclaimer at the beginning. "Blazing Saddles" used the n-word a LOT, but that doesn't seem to damper anyone's feelings on it as being a hilarious film. When shown on TV today, it usually mutes out all such words.
