You went pretty fast up the hyperbole chain there @scottalanmiller. I don't think this discussion is helpful to continue with the ways you're choosing to discuss things.
It's not hyperbole, it's just common sense. You can't say a firewall isn't a firewall because you don't feel it does enough firewalling compared to routing. That's just silly.
Anything that you use to show why that's silly, will sound ridiculous, but it's a silly thing to have to explain. It's clearly not a viable way to name things.
A router is a router, no matter how much firewalling it does. It's status as a router is absolutely based on if it routes, not "if it does other things in some quantity."
Hyperbole would only apply if the silly examples were to some degree sillier than the original language. But they are not. The "I'm a man and I'm 42" is identical in every way to "it's a router and it is a firewall." Not in the slightest way exaggerated.
