What an odd post. Speaking of irony, I find it hilarious that you feel the need to single out "tumblerinas" while inflicting us with the details of your ponderings on the nature of human kindness (apparently it's inherently insincere!).
But you still don't seem to have a point beyond that it isn't good to ignore real conflict while faking nice and it's annoying when affluent people assume all people can adopt their lifestyle.
I'd suggest you go back to basics and figure out what it could mean to be kind to others while still getting what you need and not being a doormat. Because at this rate you'll soon start accidentally quoting Mean Girls and treating it as a coherent life philosophy.
