Mufasa from BJ's doesn't consider extract brewers to be brewer's, but he's not an a$$hole about it.
Ironic, since a large percentage of BJ's own beer isn't even made by BJ's and Mufasa is in charge of their contract brewing operations. Out of their 130 locations it appears that only three actually brew on premise and supply only 30% of their total requirements.
But I digress, back to the topic at hand. Any brewers who demeans another for their methods or processes should be ashamed of themselves. At the end of the day, making good beer is what it's all about and some prominent gold medal winners were extract beers. Heck, even Jamil Zainasheff has made extract batches using slightly tweaked recipes with Cooper's-style pre-hopped extracts that he has presented to respected beer aficionados with great reviews before telling them they were drinking a 'kit and kilo' beer.
Make what you can, make it well, and tell those jerks to go to H*ll....
