Yeah, but that isn't the PTC or similar groups, its the competitors and advertisers. Probably for a couple reasons:
1. All the parties that a hypothetical family oriented group might try to leverage, are *already* moving against it.
2. Its wrestling, very few people care whether its family friendly ( as opposed to whether its safe for the participants ).
3. Because wrestling isn't fictional TV ( sort of, allegedly ) but a form of "sports", its not very useful for gaining greater control over TV in general
Basically, when you look at a group like the PTC, think "PETA": rife with extremism and apparent hypocrisy. The PTC isn't interested in advocacy that doesn't at least theoretically advance their cause of "gaining editorial control over all broadcast TV".
