It's not crazy. English speakers tend to use "they" when they need a gender-neutral option. This just sounds like some edgy teenager... ooh look at me, I'm using some invented new pronouns because of the injustices I've never actually faced myself.
Or is it just that you fundamentally disagree with the "need" for gender neutral pronouns and this is your way of ridiculing it? I'm afraid I don't follow your logic at all.
