Someone came up to me to tell me about the horrible goings on in Palestine. I was pretty clear - "If you open your mouth to tell me about the horrible Israelis bombing the poor Palestinians, I will KNOW for a fact that you are a moron and incapable of intelligent and rational thought. So, before going any further, if you want to prove your stupidity, by all means tell me, or better yet, let me think you MIGHT be stupid and walk away now."
The response was stunned silence. I considered it a successful result.
I am tired of tolerating stupid people making stupid comments. Conservatives need to quit giving power to PCness.
