This is not how it works my friend. If you're going to issue big fat ol' red Exes, it's incumbent upon you to justify those bad boys & not run away. If you cannot come up with a reasonable counter response, then I think you should make busy with the 'undo rating'. The 'Disagree' rating should only be used 'in extremis', in my opinion. You should undo your ratings, unless you can prove they're fair. So prove them or delete.
