I grew up in Louisville. They hate UK with such passion you can't help but hate them back. Never feel sorry for them. Ever.
Moved away for a couple of years, the hate stopped. Like I actually pulled for them in games against UNC. Moved back, the hate was reborn.
Moved to Florida in 2016. Again, Louisville seems like an afterthought. But I'll never fall for the "maybe their fans have changed" notion again.
I will pull for UofL in 4 situations only
1. They're playing KU
2. They're playing UT
3. They're playing UNC
4. They're playing Duke.
