The Kochs have donated to several libertarian causes, many of which would be considered "liberal," such as in favor of abortion. Hell, David Koch was the 1980 vice-presidential candidate for the Libertarian Party.

The people attacking the Koch brothers are from the Left--left-wing blogs, left-wing radio hosts, and so on. You don't give any reasons why my statements missed the mark, so I can only assume you have none. You may not like the phrase simply because you don't like being labeled--I'm sure the Right feels the same way.

Anonymous is just a label any anonymous people can use, and I didn't make a determination about who any anonymous people belonged to. I simply described the recent attacks on the Koch brothers, which is most definitely coming from the Left.
