You know that's self-defeating advice right? You telling me to mind my business is you not minding your own business. You clearly don't live by this principle, and I won't either. I don't subscribe to the kind of radical individualism you are promoting, and you don't either. Nobody should, we live in a society. Everybody has a responsibility to speak their mind when they see somebody else behaving foolishly. You do so, you freely share your perspective on the way other people live and so do I.
