A web browser is basically like

A half-OS within an OS.

Emacs is a good example of a web browser that is a text editor.

A browser is quite a systems based program. Why they aren't programmed in C and only C is beyond me.

I've never been to /g/ but I use Gentoo as my primary distro. And I don't really understand why you changed the question from "why is install le /g/entoo XDDDDD funnay?" to "why don't you install CentOS instead?". That doesn't even make sense and you know /g/tards find really absurd things funny, such as prepending > to every sentence and all that retarded shit.
