It also bugs me when paid writers use incorrect words. The type of liar he's referring to is inveterate.
That was my initial reaction, that he must have meant inveterate. But I looked up venerate and it could be right. Venerate = to regard with reverential respect. That's a verb, of course, but it could be used as an adjective as well. But does he venerate lying and liars, like a rascally rogue, or does he venerate the characters and comics medium?
Of course, it could just be an error.
