At the end of the day, I think this is more about method than message. Is some of what she's saying not correct? Sure. You can argue that. What you can't argue is that the talking head debating her is having circles run around him by a 14-year-old girl who won't take his logical fallacies.
I have never seen a more blatant attempt at just changing the subject to score points. She doesn't believe in GMO crops, but she doesn't state that she thinks they should be stopped. She believes they should be labeled, and yet, the host repeatedly attacks her with such appeals to emotion as "what do you say to a child your age who is going to die?"
It was great to watch these methods fail so miserably against a kid. Speaks volumes to the level of discourse, and this is CANADA. The US level is so much below this it's not even funny. Bill O'Reilly would have yelled at her and cut off her mic.
So, ultimately, she gets a 5/10 for facts but a 10/10 for debate & logic. At least she didn't resort to "when are you going to stop beating your wife" tactics.
