No, wait, it is because she trashed celebrity clothing lines, and made the mistake of calling them out and calling them "tacky". We at H.O.P.E. are a little ambivalent about this entire situation, but are starting to think of Christina as a modern-day Christ figure, persecuted for her beliefs.

A Note From The Mistress of Miscellany : Tina probably said celebrity clothing lines are tacky as a way to distinguish hers as being a cut above, not as a way of bashing her ownendeavor. Regardless, the ending is appropriate.
