Yea, I grew up in Detroit. Still go there a lot to visit family. Detroit isn't even close to Cleveland, that city is messed up. As for putting stock in sport teams, it's entertainment and it certainly impacted my life. I had a blast going to the games, watching and cheering. Didn't 'change' my life but provided a great deal of joy.
Should we give up motorcycling since it doesn't really change our lives either, other than the massive amount of joy it brings.
