Never have I met a man [Karl Marx] of such offensive, insupportable arrogance. No opinion which differed essentially from his own was accorded the honor of even a half-way respectful consideration. Everyone who disagreed with him was treated with scarcely veiled contempt. He answered all arguments which displeased him with a biting scorn for the pitiable ignorance of those who advanced them, or with a libellous questioning of their motives. I still remember the cutting, scornful tone with which he uttered – I might almost say 'spat' – the word 'bourgeois'; and he denounced as 'bourgeois' – that is to say as an unmistakable example of the lowest moral and spiritual stagnation – everyone who dared to oppose his opinion.

This is a placeholder explanation generated by the low-overhead model. It interprets "Never have I met a man [Karl Marx] of such offensive, insupportable arrogance. No opinion which differed essentially from his own was accorded the honor of even a half-way respectful consideration. Everyone who disagreed with him was treated with scarcely veiled contempt. He answered all arguments which displeased him with a biting scorn for the pitiable ignorance of those who advanced them, or with a libellous questioning of their motives.
