Should I have been more Aggressive here?

CO Min-Raised me pre-flop INSTANTLY (auto-button speed), then when I bet the flop, again I was Min-Raised at auto-button speed. I put CO on a high PP, JJ-AA, so I folded. Plus it didn't help that I didn't have good positioning. Should I have called or even RE-raised the flop? Or was this a good laydown in your opinion? I also didn't have a good read on this player b/c they had just joined the table several hands before.

Why bet first If your going to fold to a min raise. U really think he has QQ KK AA? and he just min raised preflop and post flop. If ur gonna fold to that raise check call the flop. If u wana be sure u have best hand just bet 4$ and see what he does. I think u folded winning hand. Should have atleast called and checked turn, if he bets big fold if not he probly has QJ, KJ, TJ, or even just a draw in which case he probly checks turn behind u.
