Dry stouts are light beers. They generally have a low FG and fewer calories than many other beers. Pale ales are light beers. They are lighter in color than stouts and brown ales. India Pale Ales are light beers. Historically, they were considered light beers in comparison to porters and stouts. Doctors recommended them to invalids. Blondes, wheat beers, and tripels can all be considered light beers.
So when you say that light beer sucks, it really just reinforces people's preconcieved notions about beers. It also doesn't dispell any confusion about what someone means when they talk about light beers, as that can mean many things.
Now, I might think that when you talk about light beers, you really mean lite American lagers. But even then, to cast them all as unfavorable is just an act of beer snobbery. It's clear that these beers have their place among drinkers. While you may think poorly about their choice of beverage, many people who enjoy craft beer also feel that a dry beer that isn't very bitter or malty can be quite refreshing at times. Someone on this forum always seems to be brewing a cream ale, which is essentially a lite lager brewed as an ale.
Not only do people reconize these beers as having a place in the beer world, but brewers also reconize the difficulty in making one of these beers. Because these beers are light on bitterness, hop flavor, color, and malt character, they require judicious adherance to brewing process. These beers do not mask mistakes. A person who can repeatedly brew consistent lite beers has demonstrated his or her skill and knowledge in brewing.
