When a player is new to the table and raises preflop, I would muck a hand like this even with position until I can get some read on the player. He might be one of those PLO maniacs who just pots every chance he gets, and you can wind up bleeding a lot of chips before you get that read.

Now assuming you felt he probably did have a strong PP, I would call preflop with that hand with position. but I would certainly muck to that flop bet which strongly suggests he has at least a high diamond draw to go with his pair. How is there even a decision to make on the turn? The villain is probably wetting himself with excitement believing that your flop call indicates you made a weaker flush and he is about to double up on his first hand.
