I have experienced numerous individuals irrationally argued against me when I told them blue moon was brewed by coors, not a 'microbrewery', whatever that means. I'm personally sick of having to associate every consumer product with some sort of public good or political cause. I don't like blue moon, but if I did, the fact that coors brews it would not stop me from partaking.
