What we should repudiate are not view of the non-Buddhists or the atheists but our own attachment. Once attachment is eliminated, no amount of heterodox ideas can affect us anymore. To someone who has attained realization, those ideas, no matter how extravagantly they may sound, make no difference at all. And the way to completely eradicate attachment is by developing renunciation, bodhicitta and, most importantly, the view of emptiness.
