"I go way back with Rosie and that’s not the Rosie I know. She was the most diverse and tolerant woman I’ve ever known for a long time."

"Whatever got in her head isn’t the Roseanne I know. It’s a very icy time. I’ve been a comedian for 38 years and I’ve never seen it, like Lenny Bruce said at the Purple Onion, ‘We’ve gone backwards.’ There are things you can’t say. There are things you shouldn’t say. Who makes up these rules? And as a stand-up comic, it’s a dangerous position to be in because I like pushing buttons. It’s unfortunate.... [But ABC] had to do what they had to do and it’s their decision."

Said Tim Allen, quoted at Entertainment Weekly, which referred to Roseanne as "the other conservative sitcom star."

Popular TV shows canceled for political reasons...

...  that's what I googled as I was thinking about ABC's canceling of "Roseanne." I realize we could argue about whether reacting to an expression of racism is political, but: 1. Racism and the pressure to strictly sanction it is political, 2. "Roseanne" has been under attack all through its reboot season because Roseanne has expressed support for Trump, and 3. That's what I googled, because I wanted to know what else might belong in the same category as the canceling of "Roseanne."

I mean, you've got a very popular show. It's making money for the network. Some large segment of the American public wants to watch the show. Under the circumstances, it's a big deal to ax it. Has it even happened before.

The main thing that came up in my search was the cancelation of "Last Man Standing," one year ago. At Vox, Todd VanDerWerff wrote "5 reasons ABC might have canceled the Tim Allen comedy Last Man Standing/Only one involves Trump."

It’s not often a network cancels its second most-watched comedy in a sudden, surprising move. Usually, if a show that important to a network has to go out, it’s granted some sort of “this will be your final season” reprieve.... The cancellation has left some conservative pundits wondering if Last Man Standing was canceled because Allen himself is conservative, and his character on the series is as well....

I think there are a bunch of really good business reasons for the show to end — but I also don’t know that its increased reputation as “a sitcom for Donald Trump supporters” didn’t hurt it just a little bit...

Any time the only show of one type or another, even if it’s “the only sitcom headlined by a major Trump supporter,” leaves the air, it’s hard not to wonder.

There's also the old Bill Maher show, "Politically Incorrect":
