It is known that 100+ IBU is no longer perceptible as 100 is the max bitterness we can discern. Even regular IPAs weigh in at 50-60 IBU so they are also extremely bitter in the scheme of beers. Most styles of beer are 10-30 IBU. In general IPAs turn the hops component up to 11 in beers. And I do think IPA drinkers enjoy it. It isn't just flexing I think (although I am sure there are some that do), because I see in beer distributors that other styles I enjoy like Belgians and stouts are cleared out for more IPA space. And I think due to the intensity of the taste, that they get more and more conditioned to find other beers not bitter enough and not floral enough in notes. It is market demand now but I think it is self limiting because once people are in the category of "IPA drinker" I find many of them drink nothing but IPAs and then eventually get sick of them.

I personally will drink an IPA from time to time, but will gladly drink any style really and particularly like stouts, German/Belgian beers. I also agree with the other child comment and will crack open a Budweiser gladly on a summer day on the beach. It is actually a very well executed beer, it is designed to be smooth and mild. I think the aversion to lagers is some amount of snobbery. I don't drink beers for image so don't care!
