The WHO very blatantly lied about masks in the beginning to preserve protective equipment for frontline medical personnel. They then changed their tune afterwards. Do you think the science on mask wearing suddenly changed - or do you think they were lying to people because they thought it the lesser evil? Framing this as a right or left thing is not constructive. Deal with each thing point by point with citations if you want to have a real engagement about the issues.
