That‘s something I believed 10 years ago, I honestly don’t see how that position can still be defended. What happened is the fascists benefited so much more from anonymity than any opposition.
But I also don’t expect that removing anonymity would in itself improve the current world, things are at a point where people living in democracies are openly advocating for the destruction of every single liberal ideals. Sure that’s in part astroturfed by anonymous accounts but way too many people couldn’t care less if they real identity would be linked to those claims
