Just some of my personal "US Policy":

Murder (unlawful killing) is always wrong. Lawful killing (war, police) is sometimes wrong and sometimes needed. Kilmeade's statement advocating killing is abhorrent, and Kilmeade subsequently apologized for his "extremely callous remark".

I also disagree with Dowd's statement. People have self-control and can break the links between thoughts, words, and actions. But self-control is a limited resource that can be depleted. Some pray "lead us not into temptation". The politicians who are assigning blame to millions of people, and suggesting violence, are leading some into temptation.

Social media and the 24 hour news cycle are not helping. There are good nutrition habits, and also good information habits. Watch what you eat. Watch what you watch. Pay attention to signs of poor nutrition (over-weight, blood pressure) or poor information intake (anger, fear, hate towards people you rarely see in person or don't know in depth).
