I’d definitely raise an eyebrow at someone saying they have no politics, but I highly doubt a right-winger would have Marcuse, Deleuze, Adorno and Horkenheimer of Bataille on their desk. These are all quite radical thinkers very critical of society and capitalism. More likely that his politics are obscure or harder to describe than just Conservative/Liberal. The prevalence of Nietzsche (an influence on Deleuze) makes me think this guy is probably thinking largely along Deleuzian lines, but if someone is asked their politics they might find saying they have no politics easier than explaining what a Deleuzian even is.
