the apple doesn't fall far from the tree- in this particular case

In 2005, Vonnegut was interviewed by David Nason for The Australian. During the course of the interview Vonnegut was asked his opinion of modern terrorists, to which he replied, "I regard them as very brave people." When pressed further Vonnegut also said that "They [suicide bombers] are dying for their own self-respect. It's a terrible thing to deprive someone of their self-respect. It's [like] your culture is nothing, your race is nothing, you're nothing ... It is sweet and noble—sweet and honourable I guess it is—to die for what you believe in." (This last statement is a reference to the line "Dulce et decorum est pro patria mori" ["it is sweet and appropriate to die for your country"] from Horace's Odes, or possibly to Wilfred Owen's ironic use of the line in his Dulce Et Decorum Est.) Nason took offense at Vonnegut's comments and characterized him as an old man who "doesn't want to live any more ... and because he can't find anything worthwhile to keep him alive, he finds defending terrorists somehow amusing." Vonnegut's son, Mark, responded to the article by writing an editorial to the Boston Globe in which he explained the reasons behind his father's "provocative posturing" and stated that "If these commentators can so badly misunderstand and underestimate an utterly unguarded English-speaking 83-year-old man with an extensive public record of saying exactly what he thinks, maybe we should worry about how well they understand an enemy they can't figure out what to call."
