or why functional programming in C should be banned(specifically GObject). I tried to open 9th window of mousepad(a notepad replacement) and its been 2 minutes since this bloated PoS is still not loaded(file is ~20kb).

nothing more pathetic than using C and trying to roll your own language constructs to pretend you're using a proper high level language. it always ends up being buggy.

"functional" programming in C always devolves into hairy stack/funcpointer macro code which can't be debugged and isn't as flexible as real functional programming.
