Why are people so against feedback, unless the person is being rude I do not think that it is a bad thing. Yes it may feel like the person is attacking the character or story you work hard at but if you like the story and it is written the way you want it to then don't worry about the comments. You never know but one of the comments may give to a total different view to you story, another angle that you hadn't thought about. Acknowledge other's good opinion even if it seem a bit mean and delete the rude and hurtful ones.
