What else would you expect when someone's entire experience with critical theory is some wanker using it to poorly advocate a pet cause?

Now that wanker's position may be well founded in critical theory and have good arguments supporting it, but that doesn't matter. When someone uses critical theory as a magic "I'm right" box, rather than helping their detractors acquire the tool-set with which to criticize (or come to agree with) their position, that behavior just makes them an even bigger wanker.
