Poseurs are people that look like punks, but they did it for fashion. And they were fools, they'd say, "Anarchy in the UK". See? Poseurs. What good is that to those of us in Utah, America? You don't live your life by lyrics.

Our reading
An editorial interpretation.
The speaker defines poseurs as people who look punk purely for fashion, and mocks those who parrot slogans as if they meant something. Living by lyrics is not real conviction, especially for those in Utah. The tone is scornful, insisting authenticity comes from lived experience, not costume or catchphrases.
