Dawkins is probably the most famous humanist in the world. His book The God Delusion was a best seller. He was awarded Humanist of the Year 24 years ago.

That is all it takes to get cancelled nowadays.
And soon the Government will pass a law so people can try and get you jailed for such a tweet.
UPDATE: Two other recipients have done an excellent letter spelling out why the cancellation goes against everything that AHA claims it is for.
