Roger Luckhurst disagreed with critics who perceived the New Wave in terms of rupture (he gives the example of Thomas Clareson), suggesting that such a model "doesn't quite seem to map onto the American scene, even though the wider conflicts of the 1960s liberalization in universities, the civil rights movement and the cultural contradictions inherent in consumer society were starker and certainly more violent than in Britain." In particular, he noted:The young turks within SF also had an ossified 'ancient regime' to topple: John Campbell's intolerant right-wing editorials for 'Astounding Science Fiction' (which he renamed 'Analog' in 1960) teetered on the self parody. In 1970, when the campus revolt against American involvement in Vietnam reached its height and resulted in the National Guard shooting four students dead in Kent State University, Campbell editorialized that the 'punishment was due', and rioters should expect to be met with lethal force. Vietnam famously divided the SF community to the extent that, in 1968, 'Galaxy' magazine carried two adverts, one signed by writers in favour and one by those against the war.
