I understand your qualms, everybody has them. But aiming for validation is really a good thing because the validation plugin will then immediately notify you about screwups, by refusing to display that green checkmark. Also a validating page puts you at least on some common ground with the browsers. That way you can focus on the known, documented inconsistencies without potentially adding new side effects through parsing errors.
