Earlier quoted context omitted.
We didn’t really learn much about the communists in the Dispossessed. Most of the novel is about the anarchists. Anarchists generally get along with communists even worse than capitalists do, so I don’t think this distinction is just pedantry.
As the linked article mentions, The Dispossessed was inspired by the works of Peter Kropotkin, the prominent anarcho-communist.
My experience of anarchists is such that I happily group most anarchists together, and place them ideologically far, far away from Stalinists.
Are you thinking Kropotkin’s ideals are close enough to communism that I shouldn’t belabor the distinction?
