AQo against a large field with an ace exposed.

Here's the situation.
Live 3/6 Holdem' Caesars Indiana.
Good table loose and VERY passive.
I'm in MP2 with AQo.
It's important to note that there are two people behind me who have called every hand that i've raised. So it's reasonable to believe that if i raise from MP2 then i'm getting AT LEAST two cold-callers behind me.
The dealer exposes an A while dealing so it becomes the burn card.
UTG, UTG+1, UTG+2, MP1 all limp and it's to me. Do i call or raise (i don't believe folding to be an option given that (apart from me) there is about 1 raise for every ten hands at this table. In fact, the only raises that i've seen other people make are with AA, KK, or QQ. Everybody is limping with big suited broadway AKs, AQs...and JJ-22. So the table's very passive as i said.)
I think that I should call given that I have a hand that doesn't play well multiway and I should expect to take this hand up against at least seven opponents (4 limpers who will call the raise, two expected cold-callers behind me, and at leat one of the blinds) and one of my aces is gone. What do you guys think?
