The front in der Kulturkampf that formed around this game was about being horny online? I still can't wrap my head around this.
It depends who you talk too. I used to discuss with a couple of big Kojima fans and they bought hook, line and sinker that he is a visionary thinker and that MGSV, as per his usual hyperbolic pre-launch marketing, was gonna tackle
taboo subjects in groundbreaking ways (also be a gaming revolution while we're at it) and they'll continue to bombard you with shallow walls of text to prove it (fyi, they clinged on "child soldiers" as the pittance for those grand claims), should you engage one despite MGS having a pretty childish and boilerplate understanding of War (basically bad things happen because of a secret cabal of bad people, mostly American by matter of coincidence, any political discourse being an empty front) while being enamored with an extravagant romantic version of the warrior's ethos.
Quiet being a flashpoint isn't that superficial when you consider that it's a pretty glaring example of Kojima gaslighting. As usual, he assured everyone there was some big deep meaning behind the character and that the critics would eat crow in shame when the game would release and provide context but to the surprise of no one it was all teenage fantasies on steroids. It's an apt symbol for his work in general.
