I'm fairly mistaken you've mistaken me on two counts. I've chastised no one. I've merely observed aloud that the choices we all make have effects on both ourselves and others.
I also don't do any such thing as block the world out in my own head...not really sure where you could have gotten that except perhaps from a misunderstanding of meditation.
The meditation that I and many practice is about peaceful abiding or compassionate awareness. It's about changing our own judgement of reality as it is, not escaping from it.
