They need not be infallible; they only need to be more perfected & blessed, compared to us. Such is their Tapas & Pakvatva that even if their rulings were not absolutely perfect, it would be capable of yielding fruit for us.

As for the unfortunate ones who think that they are superior to Śiṣṭas, they have the option to indulge in whatever transgressions they please, provided they don’t cause impediments to those who wish to follow Śiṣṭācāra. They exercise that option anyway. Who stops them?

But those who believe in & uphold Śruti, Smṛti & Śiṣṭācāra, even though they don’t stop anyone from violating those three sources of Dharma, are free to critique the violators.

One can (figuratively) spit in the face of Īśvara, Śruti, Smṛti & Śiṣṭas by virtue of his or her choices, sure; but you can’t expect those who respect them to approve of said choices, let alone embrace, welcome or praise them. //End
