Stronger: Even if we were in agreement about right and wrong, that doesn't mean that we agree about what to do. We agree that homelessness is bad? Great. How should we fix it? There we may still differ, even if we agree that homelessness is a problem that we should try to fix. How sure am I that my preferred policy is more likely to work than your preferred policy? I would say that at best I am only about 70% sure.

The problem comes when I act as if I am certain that my policy proposals are better than yours - and, worse, that you are therefore evil for proposing such flawed policies as you do. We assign to policies a certainty that they don't deserve.
