My brother works with him and says that Jake is a die-hard BYU fan and supporter. He loves BYU and wants nothing more than to see continued success for BYU. I know he attends a lot of the men's basketball games and, I suspect, a lot of the football games as well.
I guess if someone expresses anything but glowing praise for BYU they are anti-BYU, or at the very least they are not fully invested.
If that is the standard to be applied, then that would include a large majority of us here on CB as it seems there is plenty of that going on here.
