We usually pick a favorite sports team because of our location (in some cases because of religion or that our parents attended). Why do we have a favorite sport anyway? I don't pay any attention to the NBA, I don't care for the style of play. Nor ice hockey, nor soccer. I might watch a few minutes of the odd game there. Girl's softball? Same.
I figure any NASCAR I watch are excerpts on youtube for 2 minutes, if that. Friends of mine have told me that going to an event is very different and a something. Maybe I should. I used to watch a bit of golf back in the day. There might be a guy I liked that day, Tiger or Jack, for the tournament. I think one tends to favor one team over another in watching some random sport, often for us it's the underdog. If "we" watch ND play Marshall in CFB, most of us will pull for Marshall until the game gets to be a blow out and then we turn the channel.
As for the OAM thread in A51, it is typically "unusual" and I'm not sure anyone reported anyone, not that reporting someone makes a difference with very few exceptions.
