Okay, but this is my comment:
Your average age of the original antifa is 98 years old - WW2 veterans
As far as I know, the first people to physically fight against fascism are WW2 veterans. Of course, antifa does not imply only physical fighting, but in context here of the US Govt labeling antifa a violent terrorist organization, it makes sense to bring up the first physical antifa fighters were fighting at the US Govt's demand against fascism.
