He'd extrapolate that because he is a quack.
Derrida did a good job of showing certain biases in the system, as well as some dichotomies that we do have in society. But as I said upthread, he then tried to break everything down into some "x has y and y has x and they are at conflict" scheme, which doesn't always work.
Said "responsible" action is only "irresponsible" if one has infinite resources and time. Otherwise, it's called "reality". In Derrida's world, there is NO way to be moral. Either you do nothing (which is immoral) or you do something (which is immoral, because you did X instead of Y). The only MORAL answer (doing everything) is obviously impossible. Which is why it's stupid.
