The implication is that the Republicans are wrong and the Democrats should challenge it. In other words, "Hey, Democrats, here's an argument you should use." That's partisan.
I think that's the only sentence / segment in the whole talk that refers to one party or the other. Indeed, this talk is relevant even in countries where neither party exists. It seems a heck of a lot less partisan than what passes for news on a daily basis around these parts -- pick your cable news network of choice.
What? No. As an outsider, it is yet another example that both your parties are perfectly worthless. "Hey, Democrats, here's an argument you should use" is only partisan if there was a snowflake's chance in hell that they'd actually do something. But the Big People with their arms in the puppet on the right don't want that just as little as the ones fisting the puppet on the left.
