In a Medium piece by the often insightful Roxane Gay, she says she was attacked online for being dismissive of domestic abuse because she found the show Big Little Lies derivative. (From the context, that's like being accused of being pro-murder because you don't like CSI.)
She later says Trump's cries of fake news allow genocidal regimes like Myanmar's to use the same phrase to deny their atrocities. But but but...
1. Gay discusses how people attribute things to her which they've no right to do.
2. Cries of Fake News had been used ubiquitously (indeed, perhaps more by the Left than the Right) before Trump took the ball and ran with it. Denial of the ongoing Rohingya genocide cannot be attributed to Trump. (Bill Clinton's affairs were not responsible for Jacob Zuma's polygamy.)
3. Gay later says she's probably used similar lines of reasoning against her online adversaries as they have against her, falsely attributing belief and opinion. (I'd argue she's done so here too).
I wouldn't say anything but it's just that that Tucker Carlson fella and his ilk run rings around these kinds of arguments.
