Just to be sure, everything however slightly suspicious must be banned. It does not matter now if it is published by mainstream presses, just ban it, then ban it again, bury it, dig it up and ban it again.

“Peterson, a psychology professor at the University of Toronto, first became famous by his public opposition to compelled use of gender-neutral pronouns and became an international celebrity for online lectures, free speech stances and a bestselling book. Whitcoulls did not explain any connection between Peterson and the Christchurch tragedy or the alleged gunman. Among his fans are some white supremacy adherents, but neither Peterson nor his book is referenced anywhere in the 74-page manifesto allegedly released by the killer prior to the March 15 attacks. The treatise says the murder spree was in response to Muslim immigration, characterized as “an invasion” threatening the white population. Peterson did a series of lectures and engagements in New Zealand and Australia in February.”

     Oh well, it pays to be sure, who knows where politically incorrect sentiments may lurk.
