Well, while windmills are never going to replace fossil fuels, I'm going to have point out one thing here:
The goal of the Rodents is to destroy the fossil FUEL industry because they're anti-freedom, anti-capitalist parasites who have been told by their Masters to hate Big Oil.
However, the fact that the de-icing compound was petroleum based isn't really relevant. Not that the morons who follow the cult of Global Warmingcoolingnotchanging Socialism can be expected to understand this.
