Did not know that, I assumed places like SMU, TCU, even Notre Dame would not kick you out for having a beer but wouldn't encourage and sell it either. Those should be the last stadiums selling beer on game day.
I think you'e mistaken in your assumption Christian churches are wholly anti-alcohol.
Just shows how many churches have gotten away from the bible.
Pretty much all churches consider drunkenness a sin, but most having nothing against modest drinking.
