Indeed. It would be great if everyone who claims that gender neutral pronouns should be used could give a few examples, at least for us non native speakers. I get strange looks whenever I refer to people (hypothetical, or not) as "it", which would be the obvious gender neutral pronoun.

Currently it's 'they'. Yes, there's some confusion about whether it refers to one person or more, but that confusion already exists with 'you', in all except regional usages.

The difference is that "you" can be grammatically singular or plural, whereas "they" is definitely grammatically plural.

"they gives me the shivers"

In, "they give me the shivers", they is singular.

You did see that I made a distinction between grammatically and semantically, right?

Grammatically, the "they" is clearly plural, as it is used with the plural verb form "give" and not the singular "gives".

Look up "subject verb agreement".

"they" and "you" act exactly the same way. Which is no surprise, because both are originally plural. What difference are you referring to?
