Cancel culture has claimed another victim.

This time it was Dorian Abbot, a physics professor who was scheduled to talk at MIT about “climate and extra-terrestrial life” — except he committed the sin of expressing differing beliefs about diversity. He published an opinion piece that argued diversity and inclusion politics were undermining the primary mission of universities, which is to teach.

That triggered a stream of outrage from the woke Twitter mob, which used social media to browbeat MIT into cancelling Professor Abbot’s lecture. The progressive Left is so consumed with identity politics it is attacking any differing opinions, and kneecapping reason and truth, in the process.

When will it stop?
