Question: Does one tear nowadays (that we are in exile among Nochrim who constantly blaspheme)?

Answer #1 (R. Yosah citing R. Yirmeyah citing R. Yochanan): From when blasphemers increase, people ceased to tear.

Question: Does one tear for Kinuyim?

Answer (and Answer #2: to Question (a)): We learn from the following. Reish Lakish was walking in the street. He encountered a Kusi. [The Kusi] blasphemed, and [Reish Lakish] tore. He blasphemed, and he tore;

[Reish Lakish] descended from the donkey and punched him on the heart, and said to him "son of Kusim - does your mother have enough clothes to give to me [for all the clothes I tear over your blasphemies]?!"

Inference: This teaches that we tear for Kinuyim (surely the Kusi did not know Hash-m's special name), and [Reish Lakish holds that] we tear nowadays.
