Oatmeal stouts usually contain less than 20% oatmeal, or sometimes it's not mashed but instead removed before the mash. it's the exception that proves the rule, and anyhow why would the English pay attention to a German law? And oatmeal (and wheat) thickens a beer without adding much alcohol, whereas rice or corn thins it out while adding lots of alcohol (i.e. contains lots of fermentable sugars). I'm not being ridiculous, I made my own beer from grain for about 15 years. You can make a case of beer in your kitchen for about $5 without resorting to corn or sugar.
The beers that you mentioned liking are %100 percent malt, and all the beers you said you didn't like have rice / corn fillers. Adding rice and corn makes it taste shiteety, as well as using miniscule amounts of odorless high-yield hops and specially engineered yeasts that ferment every last molecule of sugar in the grains, removing flavor and lowering the amount of grain required to yield a certain percentage of alcohol. Then they run commercials touting 'specially engineered yeasts' etc. The weird flavor of bud comes from lots of rice, while the weird flavor of something like Milwaukee's Best (what's the worst?) comes from corn and / or straight beet sugar. Coors et al have different proportions.
