Good thing they didn't have network TV in 1933. Can you imagine the attack ads against supporters of the 21st Amendment? $congressman is soft on booze! He supports drunkards who destroy families and abuse your children! THINK OF THE CHILDREN!
Politics seems not to have changed much I reckon:)
I don't know why that is, because I've heard of plenty of harassment and vandalism against conservative supporters (or were they opposed?) of California's Prop 8 as well, but it didn't get much media coverage. I don't believe one can say that either liberals or conservatives are more "enlightened" overall, at least in matters of raw politics.
