not a political difference

I can have a political difference with a libertarian. We disagree on the proper extent of government involvement. That's a political difference.

I can't have a political difference with most conservatives. They want to deny dignity, remove protections, and (in some cases) end the lives of people with whom they disagree. This is not a political distinction; it is an ethical one. What is the point of a discussion with someone who is so ethically bankrupt?
