Kindness is not weakness

I am of the firm conviction that kindness is the best policy - the one which will bring us furthest in life and as a species. Yes, in fact, I think the world will become a better place if we let kindness be our favorite reaction pattern when we interact with the world.
There is only one problem in this. There are people who confuse kindness with weakness, and some of these people will do their utmost to exploit such weakness for their own benefit.
And as such, there is only one way to meet that kind of people. They must be kindly, but definitely, be told that the exhibited behaviour is kindness, not weakness. And furthermore, that it must be considered most reasonable that we invest our kindness in people who recognize it as kindness and who therefore will not attempt exploit it.
