So, some guy on an internet board starts out a thread with "I think the most debated topic in the “Firearms Industry” is the use of the front sight or not using the front sight."
In internet chatrooms and the letters column of Guns'n'Gear mags, maybe.
Generally, though, most everybody with serious credentials says one thing, and a handful of guys (most who coincidentally have techniques named after themselves and epaulettes on their shirts) say a few other, different things.
Incidentally, I'm planning to name a technique after myself, start teaching an "intense, high round count course", and let folks dump a case or two of ammunition into the berm unsighted from the hip for two days. That way I make money, and they get to take home a certificate and tell their friends that they're "trained". And since the odds of them being in a shootout in suburbia are slim to frickin' none, we're all happy. It'll be awesome. I just need to think up a name for my technique and order some shirts with epaulettes.
(Folks, you own every bullet that comes out of your gun and everything it touches. If you can't control exactly where it lands, you have no business toting a pistol in public. The easiest method for doing this (outside of arm's reach, anyway) is to use the sights that are conveniently built into every pistol.)
