Hey that’s a fun little quote, where did you get that. I wonder what “Distorters of Marxism” he was talking about? Could he be talking about “Liquidators”, i.e. people who wanted to disband the social-democratic party of Russia in favor of joining with legal parties? Nooo, that’d mean you were quoting something dishonestly, and that just couldn’t be.

I’m asking you to read “Left-communism: An infantile disorder”

Which I shall quote now

"All compromise with other parties . . . any policy of manoeuvring and compromise must be emphatically rejected,” the German Lefts write in the Frankfurt pamphlet.
It is surprising that, with such views, these Lefts do not emphatically condemn Bolshevism! After all, the German Lefts cannot but know that the entire history of Bolshevism, both before and after the October Revolution, is full of instances of changes of tack, conciliatory tactics and compromises with other parties, including bourgeois parties!
To carry on a war for the overthrow of the international bourgeoisie, a war which is a hundred times more difficult, protracted and complex than the most stubborn of ordinary wars between states, and to renounce in advance any change of tack, or any utilisation of a conflict of interests (even if temporary) among one’s enemies, or any conciliation or compromise with possible allies (even if they are temporary, unstable, vacillating or conditional allies)—is that not ridiculous in the extreme? Is it not like making a difficult ascent of an unexplored and hitherto inaccessible mountain and refusing in advance ever to move in zigzags, ever to retrace one’s steps, or ever to abandon a course once selected, and to try others? And yet people so immature and inexperienced (if youth were the explanation, it would not be so bad; young people are preordained to talk such nonsense for a certain period) have met with support—whether direct or indirect, open or covert, whole or partial, it does not matter—from some members of the Communist Party of Holland.
After the first socialist revolution of the proletariat, and the overthrow of the bourgeoisie in some country, the proletariat of that country remains for a long time weaker than the bourgeoisie, simply because of the latter’s extensive international links, and also because of the spontaneous and continuous restoration and regeneration of capitalism and the bourgeoisie by the small commodity producers of the country which has overthrown the bourgeoisie. The more powerful enemy can be vanquished only by exerting the utmost effort, and by the most thorough, careful, attentive, skilful and obligatory use of any, even the smallest, rift between the enemies, any conflict of interests among the bourgeoisie of the various countries and among the various groups or types of bourgeoisie within the various countries, and also by taking advantage of any, even the smallest, opportunity of winning a mass ally, even though this ally is temporary, vacillating, unstable, unreliable and conditional. Those who do not understand this reveal a failure to understand even the smallest grain of Marxism, of modern scientific socialism in general. Those who have not proved in practice, over a fairly considerable period of time and in fairly varied political situations, their ability to apply this truth in practice have not yet learned to help the revolutionary class in its struggle to emancipate all toiling humanity from the exploiters. And this applies equally to the period before and after the proletariat has won political power.
