Jayapataka Swami: Here the actual words were, if you blaspheme someone or ninda. Someone who is not worthy of criticizing. If someone is critical of Srila Prabhupada, Krsna or the guru, you can defend Krsna, you can defend Srila Prabhupada, or guru, or you can not  – if someone is worthy of respect and you don’t offer him respect that is called langia, neglect, and so, we generally offer respect to those who are worthy of it. If Srila Prabhupada said as a brahmacari, I should offer respect even to the mayavadi sannyasis, but not to engage in discussion with them. So when one is not on that level that they are worthy of respect, then one can just avoid them. No harm to say Hare Krsna and then don’t discuss, if you know such a person is a vaisnava aparadhi.
