I've been pretty clear and never tried to hide that I grew up rooting for Utah. I also went to BYU and married a BYU grad. I root for BYU and want them to do well. I also enjoy seeing Utah do well and have fond memories of watching childhood games with my dad.
If your definition of being a BYU fan is wanting BYU to do well and caring about their success, then, yeah, I'm a BYU fan. But I guess if your only definition of being a BYU fan is hating Utah, then I fail by that metric. I guess I just don't believe being a BYU fan is primarily about hating Utah, but if that's the most important part for you, I don't know what to say.
Side note: The evidence you are continually posting has me actually saying that I think BYU would beat Utah this year. I'm definitely not going around claiming BYU is terrible.
