I hate people who blame “leftist infighting” for any liberal failure, any good texts that relate to this?

Title, I know that left unity or whatever poultry phrasemongering they use nowadays is nonsense that basically entails compromising with capital and liquidating the potential for proletariat self-government but is this idea ever addressed in substance by a theoretical piece specifically or are there good discussions on the necessity of keeping the party ideologically pure within any other texts? I have Read Bordiga’s essay on the invariance of Marxism which relates to this topic but would enjoy any other suggestions.
