Their book starts promising 😂️
Why is Stalinism-Hoxhaism irrefutable?
Because it derives from Stalinism and Hoxhaism.
A great deal of the first part of the book is just saying "Stalinism-Hoxhaism is this", "Stalinism-Hoxhaism is that".
Stalinism-Hoxhaism is the ideology of the revolutionary fighters for world communism of the present, characterized by the revolutionary militant spirit of the heroic times of Marx, Engels, Lenin, Stalin, and the Comintern.

Stalinism-Hoxhaism is the strongest ideological weapon of the world proletariat for its liberation from world capitalism, for the construction of world socialism and its transition to world communism.

Stalinism-Hoxhaism is based on the 5 Classics, but not limited to their lessons. Marxism-Leninism was further developed even after the death of Marx, Engels and Lenin.
It reminds me of the Marxists-Leninists-Maoists, who usually have very pompous words for their ideology (they praise their theory because they cannot set an example through practice). It just seems like watering down of Marxist theory, because the more away you are from the fundamentals (Marx and Engels), the less coherent any Marxist theory becomes.
Marx/Engels and Lenin are not only complementary but a coherent whole because it was in Lenin than the theoretical and political basis of Marx and Engels became concrete. Marx and Engels were the theory which Lenin gave a practice to (or, rather, praxis). There's no need to reinvent the wheel. Stalin, Mao Zedong, Hoxha, all were Marxists-Leninists, and their theory/practice only serves to make Marxism-Leninism flourish further.
Though we would write about Marxism-Leninism-Maoism because there are several organizations which take that ideology as their guiding theory, there's no need to write about Stalinism-Hoxhaism, nor this on-line "Communist International" because it is extremely irrelevant. So my advice is to not bother. If you happen to find anything about this further, feel free to add it up, though.
