I don't think Glanville's comment warranted any criticism from Yahoo which tends to criticize everything. Brokeback Mountain was a silly movie imho and I think it was apparent that Glanville was not alluding to the underlying theme of the movie but merely a reference to its title.
FWIW, Glanville attended an IVY-League school and is indeed no dummy. He was a member here at the hsbbweb for a time.
