As a biker, I hate these types of riders with a passion. All street legal bikes come out of the factory with reasonable sound levels, they have to go out of their way to specifically make it uncomfortable for everyone else. Pretty much every one of them is exactly the type of person you'd expect as well, insecure with an intelligence level comparable to a wooden spoon. Personally I tell nearly no one that I ride bikes, because the first assumption is always that you're one of those loud assholes.
