Roseanne is just one of many examples of awful people getting called out for being awful, and then running to the hard right, where not only is their awful behavior ignored, it's actually embraced.
Elon Musk is the gold standard of this, and of course, Donald Trump practically invented it.
Fascism is an ideology that rewards people for being the worst version of themselves.
Roseanne might have corrected course after her racist tweet had the right wing not embraced her.
This is why MAGA Republicans are a cancer. Their hatred spreads and consumes.
