Should Colts fans root for or against the Steelers in SB 45?

a FB friend of mine called me a Jets bandwagon jumper because I was thankful of the Jets for eliminating the Colts (I HATE the colts, Fins Fan tho) and he says "AFC all day" and I responded by saying the Colts fans will root against Steelers. If Steelers win SB 45 Big Ben & the Steelers will 1 up Manning & the Colts again with that said should colts fans root for or against their AFC brothers/rivals???
