Re: Is this just an English thing ?
"Of course, we have a perfectly acceptable gender-neutral pronoun in English:"
"They" is the gender neurtral pronoun for people, and it has been in use since the 14th Century.
The use of the word "you" as a singuar pronoun is much more recent than that, so if you think "they" is gramatically incorrect, then you will have to start addressing people in front of you as "thou/thee/thy" instead of "you/your".
