Why would it be a double standard for "right wing watch" to not repost left wing content? (EDIT: For the record I am all for a "left wing watch" that only reposts influencial left-wing's voices that the posters believes violates terms of service on the website they post on. I just don't understand why "right wing watch" should be expected to do so, or why it's a double standard if they don't.)
