"people don't just start liking or supporting BYU because they like you as a person."
Honey catches more flies than vinegar right? They may not like or support BYU but it certainly doesn't help when people are rude. My initial dislike for BYU was based on how BYU fans (including friends and family) treated me as an Aggie fan. I have since softened my dislike due to good interactions with BYU fans. While it is true that I will likely never "support" BYU but it might fianlly catch up to Utah in my feelings of "I hope they win every game that we don't play them."
