Liberal hatred? There's an app for that! When you get right down to it the left hates the Koch brothers because they're successful and they use some of their money to spread conservatism. George Soros is a near liberal mirror image. Yes, conservatives criticize Soros, but rarely is he demonized. The left sees the Koch brothers as the root of all evil.
And the effort to boycott them is laughable. They employ thousands of people in good paying jobs. But why let a little reality get in the way of hatred, huh?
