I'd call here. MP2's range is super wide, so he could be raising with tons of crap we beat just because "omg I have a pair!". And if the BB calls behind, even better.

Why raise and force them both out with a hand that currently only has medium-strength showdown value and lots of room to improve? You're just turning your middle pair into a bluff, when it will work much better as a bluff catcher against these fish.
