Paraphrasing (26st paragraph)

Text

The faces and slogans on the fringe left may have changed, but the mindless idealism remains. The Quebec protesters cared deeply about many things, but sadly, not about the truth.

The main idea of the paragraph

Unfortunately, the anti-free trade left remained unaware of what economics is, and while organizing protests in Quebec, they did not even know what they were protesting against.

令人遗憾的是,反对自由贸易的左派们依旧不了解什么是经济学的基本原理,他们在魁北克市组织抗议示威时却不知道他们在抗议什么。
