Standards are the One True Path. That's why they are standards. I see no disrespect in enforcing them. Even more - the ones not following them and forcing users to burn additional CPU cycles because browsers have to assume they may be parsing crap are the disrespectful ones. Come on, it's not that hard, especially with help of IDEs.
