Silly Preflop Question

Opponent is short stacked and an idiot. Fairly LAG. He raised with QJo preflop, bet pot on flop, and on turn with OESD vs an opponent who was basically put all in with his turn bet. I thought this was a no brainer but after seeing some of the stuff you guys fold to raises I wasn't sure.
