If you want to live a peaceful life, at least in the US, you leave well enough alone when it comes to US wars & just keep your trap shut. Those in the countries facing war, occupation, genocide don’t have such an option. Neither do those of us with family members eligible for military duty or who want to go to church or the mall without getting our asses shot off by psychos schooled in US militarism. If you care about other human beings, if you care about leaving a world suitable for children to live & love in, that well enough alone crap is not tolerable. It’s for sissies.
