Does this make me a bad Vikings fan?

Yes it makes you a bad Vikings fan. I dislike the Steelers as they're the biggest bandwagon team in the NFL but I'm rooting for them to win because I couldn't live with myself if I supported the Packers. If you go through with rooting for the Packers I'm just going to warn you in advance: no matter how many showers you take or how hard you scrub, you will still feel unclean.
