Tankies are fascists dressed in red. Idiots who see Stalin’s SSSR and Pooh Bear’s China, and lately, Swollen Baldy’s Russia as utopias and human rights violations, systemic oppression, genocide, torture and rape of ethnic groups, as necessary acts to be celebrated. The term originates from the famous Tiananmen Square photo of the guy standing in front of tanks – tankies would be the people in the tanks.
Tankies are so far off the deep end that it’s impossible to reason with them. The only thing you can do is excise them.
