I don’t see much indicating him as a former communist
He talked about it - some variety of Trotskyism IIRC. A bit of a surprise but shouldn’t have been. Tons of former Maoists have been in high positions. Even a neoliberal head of the European Commission (Barroso).
On the supposed virtues of communism, you won’t convince me but I suppose you know that already. IMO the world would have done very well to listen to George Orwell, someone who saw through it all on the basis of up-front experience 90 years ago. That might have saved an awful lot of needless suffering. Or Orlando Figes, who wrote a book whose title says it all: “The USSR: A People’s Tragedy”.
Now that is some enthusiasm for the fediverse.
