I think you'll find that this whole thing goes much deeper than just one mere game. Mario has been a tsunami of homosexual allure for over 20 years now. Forget the subliminal. Forget the concept art. Let's just look at the basics here.
Mario is a plumber by trade. But how often do we see Mario fix your washing machine during any of the games? How often do we see him work for fifteen minutes, and then charge a bill so exorbitantly pricey that you might as well be taking out a mortgage? How often do we even see as much as a wrench?
The answer?
None.
But how often do we see him sliding down plumbing the wrong way?
The entire series.
Additionally, the mushrooms. By eating these mushrooms, you gain height, or become 'higher'. Like the hippy.
Furthermore, the obsession with gold coins. Truly, Mario is obsessed by Greed. You must also consider his antagonist, Bowser. One letter from the word Browser. If one has time to 'Browse', it clearly shows that one is idle, as trademark of the lazy man.
Ecclesiastes 10:18
If a man is lazy, the rafters sag; if his hands are
idle, the house leaks.
Ergo, Mario as a whole teaches us to be homosexual, lazy, greedy hippies. On crack. Truly, a work of the Japanese Boodist devil!
