agree with this guy. I'm unaware of any doctrine or principle that states we must support BYU and/or it's athletic program. However, I'm very familiar with scriptures that identify agency as a principle and support people making "righteous judgments".
I think most, including my brothers, are able to delineate between good and bad. They hate the sin, but love the sinner. But Lifi seems to lump the two together and expects all to worship BYU.
