I have read a LOT about the flipping debate, and frankly, a poker player arguing that it puts too much gamble into the game of poker is a pewrfect example of a pot calling the kettle black.
"His cards, his play." Period
If there is discussion about how to play the hand, that is collusion, different, and actionable, but if I want to raise with two cards in my hand, then it is my choice.
So some players like to just let it ride and coinflip their way through a game? Hey! It is their cards to play as they wish.
Never played against a maniac? They are hyper loose and hyper-aggressive but they are exercising their right to play their cards the way they want to.
In my experience the whiners in this debate just can't handle the variance this kind of loose play creates and my advice to them is: play down a level.

You do not want to police the game until you get a ho-hum game without any personality edges. I recently made a read on some Pot Limit Omaha Hi $1/$2 6-player opponents to decide to push my top two pair, winning a $450+ pot against two players. I did it because I tried to push them off their hands. They stuck to their guns (AAxx & QQxx) and lost their stacks. Man oh man, the whining was unbelievable

and I typed in "My cards, My play". Still they were yapping.
Flipping as long as it is ONE player's strategy and not discussed with an opponent is a totally legit idea ... it is called "Playing like a Loose Donkey"

and should probably be encouraged!
However, be warned, in no-foldem-holdem, variance can be huge, so bring all your bravery and a mountain of cash, (and a few changes of underwear

) to play players like that.
