Its not as much that you're being berated for the hunch as everyone is trying to show you that its a very bonehead move and somewhat illustrates that your game isnt grounded in basic , stonecold facts. If the bet was being raised and reraised back, i think it's safe to say that one of them already had trips which were most likely higher than your pair of 7's meaning even if you did catch your 7 on the turn, you would be up against a very good looking boat.
Furthermore, you should never let somethine like instinct decide whether or not to call, at least not in the way you describe it here. Instinct can be used if you just know the other guy doesnt have it, if you have such a fundemental tell on him that your gut just tells you, reraise him all in cause you know he'll fold. Instinct, on the other hand, cannot tell you that A7 looks sexy cause you can just feel it hittin big on the flop. It just doenst make any sense whatsoever.
