I spent years defending the Language Poets, because I felt their project was valid, that you didn't have to rule it out of bounds, as so many wanted to do. This was not out of any belief that all these poets were equally good, or that I myself subscribed to those particular doctrines about writing. I just wanted to defend them because, well, they had some good work that I liked to read. Some of their work doesn't seem so great, in retrospect, but that is inevitable. What I didn't like, in fact, were people dismissing them because they presumably all wrote in the same way, something that was not true at all. Perloff, too, got lots of grief for defending them.
I also defended flarf. Some of it was because my friends were writing it. But once again I think I disliked the idiot critiques of it. You can say you don't like it, but you aren't allowed to make idiotic criticisms of it.
