None of this refutes my post whatsoever. The amount of JavaScript to open a hamburger menu is literally around 500 bytes. It can easily gracefully degrade just like your last sentence said. You're going to load much, much more than that by following TFA. It loads an entire new HTML page! This argument just doesn't work here.
There's nothing to refute in your post; you only told the audience that you don't get OP, and people tried to explain the appeal to you. What you do with that information is your thing.
