It is. The only evidence of a massacre of protestors in Tienanmen Square presented in that article is Wu’erkaixi’s claim that he saw 200 people shot, but he had actually left the protests hours before the final protestors left, and literally everyone else present (including western journalists) says that the last protestors left peacefully.
Edit: Here’s an overview from the former Beijing bureau chief of The Washington Post, who was in Beijing covering the protests in 1989.
Not at Tienanmen Square. Confirmed by western reporters at the scene along with contemporary US diplomatic cables later leaked by Wikileaks. Western media is really attached to that image of the guy in front of a tank, so everyone just pretends it was the site of a mass murder. Really odd.
