No offense to your friend, but this is grounds for revoking one's Man Card, haha. As my dad once said, "being a sports fan builds character ... especially when you cheer for teams from our state." The bandwagoners not only look cringe and unprincipled ... they miss out on SO much of the meaningfulness of sports. The highs mean a lot more when you feel like you have been a part of the journey through all of the lows, and cheering for a team is a lot more fun if you feel like you have an actual REASON to support that team (e.g., being an alum, cheering for your state flagship team, cheering for a school your parent went to, etc.).
