The whole point of vim and emacs is that you can do everything from the keyboard and not have to switch your hands to/from it. Fancier versions (like Macvim, which I use) support the same basic premise.
Now, certainly, with the fancier GUIs you can absolutely use mouse inputs. But it's quite a bizarre scenario where someone would be using an interface narrowly optimized to use the keyboard for everything, and yet still consistently use the mouse to exit "like every other application". The reason you use emacs/vim is to keep your hands from having to leave the keyboard! Why would you do that and yet not use the standard command for quitting? Not even ctrl/cmd-Q?
The parent is right to be suspicious of someone claiming extensive emacs/vim experience while using the mouse as a default option for a frequent, required command.
FWIW: I'm a Macvim user that has never quit it by clicking an X even though I know it's possible (at least for the individual windows). Although also FWIW I don't use the vim window feature and would fail questions about that.
