This is a highly normative opinion. Your version of integrity requires you to cow to a system that has been built for the purpose of your oppression. Your beliefs in following legal channels, turning the other cheek to abuse, and failing to defend your fellow man against dehumanization are the result of indoctrination by a system designed by the wealthy to keep themselves wealthy at the expense of the many.

I get rid of people from my life who I think don't have integrity, or whose values are different from mine in critically important ways.

On this, however, we agree entirely.
