No.
Maybe I'm way off the mark here but... I think the reaction to tankies seems very overblown. No one you could describe as a "tankie" is currently in charge of any of the countries/companies/organizations that are busy destroying the world right now, so I don't super understand why everyone's talking about them like they're at all a priority? The authoritarians that tankies are obsessed with are all either long dead, or totally unaware of their existence.
Maybe some people on the left are just trying to look at future dangers here, like tankies are gonna be "Bolsheviks Part 2", somehow come into power, and then purge all the anarchists or something. But didn't Bolsheviks actually have a lot of power and influence prior to the revolution? Tankies don't seem to.
