''Cheap toy like'' [quotative-と] say [nominalizer-の] [topic-は], cheap toy [toward-に対して] rude is.
A comic meta-comment showing the pattern 'saying X is rude to X' — a joke form that denies a dismissive comparison is fair to the thing being compared. ちゃち ('cheap, flimsy, shoddy') is a casual na-adjective. ~に対して ('toward X, with respect to X') marks the target of attitude or action. The nominalizer の turns the quoted comment into the subject of 失礼.
