Troll aside (which I doubt here, but let's be naive for a second), this kind of proposal surprises me enormously for one thing: it's something that claims to be inclusive. But at the same time it fails dramatically on one point : It is impossible, in many of today's languages, to convey the neutrality associated with 'They'. Which would mean that this kind of thing would not be accessible to non-English speakers.

Which is... rather exclusive. Just to clarify one thing: I'm well aware that if it only appears on the screens of English players, well, it won't make any difference to me. It's just the reasoning itself that seems strange for this reason.
