I'm a CFI and can understand how you feel. That being said a pilot that has passed 121 training is a better option then the ones who haven't. They know that pilot can pass the training required. They also know that that pilot already has the experience necessary to operate under 121 rules. They also know that that pilot knows what he is getting into when it comes to the 121 world.

A CFI that has never been with an airline is an unknown. Who knows if he will get through training at all let alone really get proficient.

On a side not: The way you are writing isn't helping your argument. All the "dudes" and "bros" make you sound like a kid and not a professional.
