The most basic example:
Critique of critique is critique
The more complicated example:
Critique of imposing ethical opinions is imposing ethical opinions.
For the purposes of this example, assume that "critique" amounts to suggesting that critiqued behavior (imposing of ethical opinions) is wrong. When one suggests that someone's behavior is wrong one can not help but appeal to some ethical values (maybe deep inside), and therefore impose one's own ethical opinions.
Is there any term, that may describe this strange sort of critique, that actually beats himself? Except of obvious "recursive critique".
