He's got every right to express his opinion and from the persepctive of a professional driver, he's got a very good point. Do you aim to censor him?
Cooperative use of urban roads cuts both ways: at the moment all the pressure of the cycling public's indignation is on drivers, which mostly means bus, taxi and truck drivers, who are painted as the Big Satans of the road. Anybody who has ever driven for a living and especially driven a large vehicle will understand the frustration of trying to manouever the thing safely through city traffic while dealing with work-related stress, deadlines, route-finding, safe, legal parking and the need to find an easy escape from the destination once the job is complete. A minority of cyclists has zero empathy with professional drivers or understanding of their difficulties, which indicates lack of intelligence, my definition of intelligence being the ability to think in abstract terms and to foresee the consequences of your actions. Paradoxically, many cyclists consider themself right-thinking and intellectually superior to drivers so there's clearly something that goes wrong inside their heads when these people throw a leg over a saddle.
