"We know of how America refused to accept Prohibition and, in good conscience, Americans broke the laws against the consumption of alcohol."
That statement right there, sir, proves you know nothing about wince you speak. The largest killer and the largest family destroyer in America is alcohol. Even knowing how they are losing their spouse, job, house and children due to their drinking, the alcoholic won't stop. "Good conscience"? No. The addict has no conscience about his/her decisions.
