To raise or not to raise?

Wanted your thoughts on wheather or not to raise with AKo/s in:
1) Early position
2) Middle
3) Late with a raise Reraise correct play?)
This was a subject of debate with a fellow co-worker. I say raise almost always(x>90%) to build the pot, chase out chasers who call and end up on the losing end most of the time, to earn a free card on the flop. He says no b/c he never hits a flop.
What are your thoughts???

you raise with AK because its more gooder than T4s and K9o.

Let's compare arguments, shall we?

While not completely correct, this argument is close, and is at least grounded in poker theory.

Arguments like this are why I make money playing poker. I shudder to ask what this person's raising requirements are.

AKo is an automatic raise, almost always a three-bet, and usually a cap depending on reads.
