I've had a couple of great debate/discussions over the weekend with people of differing opinions, and during those interactions the frustration of having no valid argument led one of the participants to resort to announcing, "Well, that's just your opinion, and I'm entitled to mine just as you are to yours."
Agreed! We found common ground! Except.....
We were discussing the principles this nation was founded upon, and his opinion wasn't very well thought out. So I led him down the road to reason. My opinion was grounded in the founders original design, which was inspired by the teachings of John Locke, Montesquieu, George Whitefield, the study of Greek and Roman civilizations, Plato, Socrates, the Laws of Nature, and finally the principles of the Bible. I missed a few, but you get the picture of where I was going. In turn I pointed out that his opinion was based upon the teaching and writing of Lenin, Stalin, Mao, Alinsky, and every other radical with a socialist/communist agenda.
Point being, he never thought through what the basis of his opinion was. He didn't know where the principles he espoused came from. He was simply repeating rhetoric he'd heard that sounded pleasing to him. Wouldn't it be nice if the government supplied you with all your needs? No, it always turns out as hell on earth portrayed as heaven.
Look the Bible is quite clear, we are our brother's keeper, not the government. To pass off our charitable acts to a government entity is living like a serf. Socialism has never worked because it lacks personal responsibility, that's why our founders choose to design this great nation as a republic. Challenge stinking thinking and ask them what are those opinions based upon. Then walk them back to where they were originally voiced and show them the horrors they created. If they still can't see the point, quickly walk away.
