I think this guy means "overgrown," not "fully grown."
If it were about leg space, sure -- and I'd agree that there's been a problem there (not for me).
But it's not about leg space, is it? It's about fat fucks who all say the same 3 excuses for why they're "built" like fat slobs & why others should subsidize their problems, instead of them paying for their own needs like everyone else does.
Even long-legged people have an option for an upgrade to solve their problem -- at their own expense.
