To forgive does not mean to deny evil, but to prevent it from generating further evil. It is not to say that nothing has happened, but to do everything possible to ensure that resentment does not determine the future.

In 1986, a young comedian walked off stage at Yuk Yuk's Comedy Club and vowed never to perform again. That same year, he was diagnosed with cancer. His name was Norm Macdonald, and his story would change comedy forever. Here's what happened:

Calley Means on Joe Rogan: “I used to be a Never Trumper.” “I think the two most existential issues are nuclear war and what’s happening to our health. Watching Trump care about chronic disease, watching what’s happening with RFK … there is tremendous connection of these two men and moral clarity. There’s two important questions to ask: Who sees this corruption and institutional capture that’s going to destroy our country? And who is willing to suffer that blowback? Trump has said that his one big mistake last time was personnel, that the Pharma and Ag slithered in and gave him the list of names. Everybody should ask, do you think RFK is gonna have an influence on those names based on what Trump has said? I think he is, and I think people like Elon are gonna be involved, this coalition of people that are coming together.” @calleymeans @joerogan

.@elonmusk is right: Donald Trump should not be permanently banned from Twitter. There are actual authoritarian regimes with active Twitter accounts. A better standard would be to ban any government from Twitter that restricts the freedom of speech. Don’t tolerate the intolerant.
