I am not after changing anybody's political opinion much less Churchill's followers' because they seem like a lost cause to me but if my comment could be construed as a political speech, it would be more valuable if it was targeted at enlightened people sitting on the fence and not the hardcore ardent crowd.
Just as a friendly pointer, I don't think you're going to change the mind of anyone who respects Churchill by saying that they're amoral & comparing him to Saddam Hussein. Regardless of where the truth may lie it doesn't seem like a winning approach.
