If you mean you don’t buy any beer...then find out whatever else they sell and boycott that. Or if someone offers you a beer, tell them you want beer brewed by an American owned company, but not a Belgian owned company..Every little bit helps.
I mostly drink home-brew or Yuengling. I have always liked Coors for a hot weather drink; I understand that even they support the sodomy agenda. The Bandit weeps.
