Any citation can be "perverted", if you allow me the expression. What is a buddhist ? Some with the same religion ? With the same philosophy ? With the same ideal ? The definition of this name is vast. So many people say "you are not from my religion, go away !". Wow, now, that's certainly what's religion is all about.
Maybe one valuable goal is to make our spirit an ocean, not a bucket of water with 3 fish inside : you, our family, and some buddhist friend, all that bathing in the foggy water of conditional appreciation.
There is so much suffering when the spirit is so "tight". Really, by being so conditional, the one that suffer the must is "ourself".
Still, negative people, who put you down and profess negative things : let's go stealing, let's take drugs, or drain all your energy... maybe it's better to avoid. Maybe this is those persons that are targetted by the citation given.
