100% on board with this. But I think the "dating a great guy" example is slightly off. In many languages, the masculine plural refers to a group of all men, or a mixed group.

Right, "man" being the default gender is somewhat unfair to half the population, so it's best to avoid it. Yes, this means you have to think of new words. Nobody had a problem when their phone keyboards were too shitty to type "you", so I think we can do it.
