blanket condemnation
The "overall" or "all-encompassing" disapproving verbal statement that Lucy vanPelt --- and Miss Othmar, too, apparently --- made regarding Linus's precious "yard of outing-flannel".
Before Lucy makes too big of a blanket condemnation of Linus's fabric-related "affliction", perhaps she should run a quick reality-check on her OWN life and see how many insecurities that SHE HERSELF has... she merely reacts to them in a different (and often far-more-upsetting/destructive!) way, such as screaming,. punching,. kicking things, etc., but she has said sensitivities all the same.
