That's all the more reason to harden it, not to weaken our collective defences. If you accept my stance that repeated exposure leads to resistance/strengthening of your mental barriers. Of course in the case of more subtle manipulation I guess you also have to be aware of the fact that the manipulation is happening. In such a case I imagine one cannot rely on a gradual hardening because exposure alone.
