I assure you, I did not need to cultivate my disinterest in professional sports.

Also, any disdain I have for the subject is entirely centered around the fans. Sports fans have a tendency to assume that everyone is a sports fan, and act accordingly. I don't shame anyone for not liking board games, don't shame me for not caring about whatever latest playoff is going on.

Also, when delays in my commute can be directly attributable to a specific event, you can bet I'm going to develop negative feelings towards it.
