Quote - Grammatically speaking, It is more correct to say "his" than "their" (as their is meant only as a plural pronoun), and it is still considered by most english professors (male and female) to be less awkward to say he, him or his when referring to an unknown gender rather than he/she, him/her or his/hers. Additionally, the US is one of the very few cultures (tho not the only one) in the world where some people consider it sexist. It many cultures, > Quote - That's pretty much old hat nowadays. Perhaps in a very nit-picking grammatical way it might still be true.  However to use the male gender as the norm is very old fashioned and extremely insulting to women.   This isn't just in the US but in the UK also.  'Their' is the only satisfactory way to say it in English, which is the language we use.
