Anyone familiar with rating site "Web of Trust" will find example after example of conservative web sites being rated poorly. Same with the usual sites such as wikipedia, digg, del.icio.us, youtube. I'm guessing the leftists out there spend their every waking moment on line and have nothing better to do than to seek out conservative entities and drub them with a bunch of fake ratings. It's a tough problem to solve when you've got 50% of the nation acting like children and you've got web sites that are at best unresponsive to the problem and at worst encourage it.
Larry Summers had an "honest" discussion about gender. That worked out really well.
The reality is that the people claiming they want to have an open, honest discussion actually don't want anything of the sort.
