There wasn't any immediate SHOCK HORROR to Graham's IT Crowd episode; it aired in 2008, he didn't get any meaningful pushback for years,
I covered that:
TW presented in a comedy in saner times as something other than a fabulous creature to be revered. . . . Time passes . . . world goes mad . . . MEN COMPLAIN!
The "immediate SHOCK HORROR" was in response to the delayed allegations of "transphobia".
They were, let's be honest, less about the content of an episode of a long gone, if much admired, Sit Com and more about wielding the Cancellation Stick with which to beat Linehan bloody and senseless, metaphorically speaking. Why? Because he supports women's rights and advocates for protection of children.
He is no saint - who is? However, to accuse him of "self-centred narcissism" seems like yet another deliberate bad-faith reading of his actions.
He has the perfect vantage point to observe and then highlight this particular example of the hypocrisy of Channel 5. So he did.
It says a lot that some people are more exercised about Glinner's motivation in putting a spotlight on Channel 5's hypocrisy than they are about the moral deficit that he identifies in C5's continuing to run MAFS despite allegations that it has enabled rape.
