which i thought was wrong.
cause like bdesmond said its not like the little men are gonna get blasted out of the speakers.
but thats what it sounded like he thought was going to happen

Actually, what he was doing was important, and neither of you are fools - you need to be able to set the fader to +10 dB during a show without the risk of feedback. I do this myself before a show - especially a musical, because our system is very prone to feedback with our lapel mics. And during a musical, the live band is often 20 strong and is quite loud, even when playing as piano as possible.
Here's what you do, just to clarify: Have the actor stand center stage with their mic on, and have them start saying their lines. Bring the fader all the way up to +10, then adjust the gain until the system feeds back. Then bring it down slightly, and have the actor walk around the stage. If he/she doesn't feed back, you're set. If he/she does, dip the gain slightly and repeat.
Btw, you need to start referring to feedback as feedback, not peaking. As IcePenguin stated, they are very different things and it's important to use the correct term when describing something to a professional (or another sound technician/designer).
