Carnival of the Liberals #51 is up at Pollyticks. My piece this time: Free Speech for Evil, Hateful, Repulsive Nutjobs? You Betcha! My favorite other piece in the carnival: Ancient African Math/Science Shatters Stereotypes, at thinkbridge.
And Skeptic's Circle #73 is up at Holford Watch. My piece this time: Short Memories: AIDS Denialism and Vaccine Resistance. My favorite other pieces in the Circle: What’s the evidence cancers are our own fault? at Junkfood Science (long, but totally worth it), and Reasons to Believe at Action Skeptics, on the differences between skepticism and woo. Enjoy!
