That depends on which generation of comics you ask the question of.

Tim Allen, whose network-television show credits now cross rival-network boundaries (ABC let him go),
spoke up publicly in defense of Roseanne [Barr/Arnold],
wanting to know whose idea it was
to say what is permissible and what isn't --
Allen allows that Roseanne's network "did what they had to do,"
and also warns that it's a danger sign
when comics get censored.
