Although attributing this to Churchill is somewhat disputed, it still can be true.“Show me a young conservative and I’ll show you someone with no heart. Show me an old liberal and I’ll show you someone with no brains.”
- Winston Churchill
My daughter was liberal politically when she graduated college. Now she is 40 and a staunch conservative. My sons didn't go to college, they went into the military. So the liberal professors didn't get a chance to influence them. Be patient, in a few years he may understand.
