The fight is always over the premises. Anyone who screws up logic or facts are amateurs. Given certain premises, Hitler was trying to protect the world. Given certain premises, ecology requires mass murder.
So the problem is that correct premises are based on morality and reality - i.e. what is worth living and dying for, and what actually happens despite anyone’s opinion.
But for liberals, morality and reality are death. So to fight them, you have to point out things that are going to make them scream literally from their fear of death - and its not pretty.
In fact, it’s pathetically ugly, and as dangerous as a rabid dog.
The left hold themselves to no standards at all. Ted Kennedy was a drunken womanizer who drowned Mary Jo and did nothing to earn his Senate seat or anything else in life, all that media praise is phony and based on lies.
Then these same people will scream and demand resignations if a Republican so much as flirts with adult interns via text message.
Rank hypocrisy.
