It's not really an issue of 'self righteous' as it is sadness.  Sadness that folks using decoys will never get the near religious experience of what pure turkey hunting is.

Using decoys is like doing 3rd grade math.... sure it gets the job done, but wouldn't you rather be proficient at calculus?  And it's NOT the fact that those who enjoy calculus look down on those at a 3rd grade math level... but rather that those doing calculus know how much more those on the 3rd grade level would enjoy doing calculus if they just tried it!

I'm not holier than thou... I used decoys for my flydown setup for a couple decades.  What I found is that what you paid for the decoy or how good it looks means NOTHING to a turkey.  Just what mood he is in.  You will have just as much success (or failure) with an inflated black trash bag as a $200 decoy.  And I'm being serious.  If you are taking you kid hunting with decoys, buy the cheapest ones you can find, then spend the difference on something that is really important (like calculus textbooks )
