I can't think of a single fic where Perry has been actually censored for doing so - by his wife perhaps, but not by the author of the fic. It is all right for a man to spend all his time at work.
Your conclusion does not follow. Perry and Alice divorced, which would seem to indicate that the writers of the show understood that a man can *not* spend all his time at work. I can't think of a single fic in which Perry's side was taken over Alice's, nor can I recall a single comment on these boards to the effect that Alice should have stayed with Perry because "it is all right for a man to spend all his time at work."
If people who didn't have anything to say one way or the other about Perry's divorce now censor Lois for doing the same thing Perry did, maybe it's not because they are sexist pigs who don't think a woman should have the right to make the marital mistakes Perry was "free" to make, but rather that they are more emotionally involved in Lois & Clark's relationship than they were in Perry & Alice's.
