Well, I'm not sure what it is that you're looking for. If you want an argument that you don't think you can refute, that means that you're having a propositional problem: you're searching for a demonstration sketched out logically.
If you've seen the arguments and don't think you can refute them, but still don't believe that they are necessarily sound, then you are more than likely having a problem about insight. This would be like the situation of somebody who really just doesn't see that the principle of noncontradiction holds, even if they know that they can't dispense with it in argument in a satisfactory way.
You may however simply both see the arguments and think that they're sound, but still have some kind of annoying emotional rejection or lack of feeling that is haunting you. This is an entirely different problem from the former two and has to be approached in another manner.

My BooksIt is precisely “values” that are the powerless and threadbare mask of the objectification of beings, an objectification that has become flat and devoid of background. No one dies for mere values.~Martin Heidegger
