Established from what? You cannot name a single person who has been even accused and was linked to OSF group but you established it?
A Trump supporter recently killed 17 children, should I use that as evidence of all Trump supporters being sociopathic child killers? Isn't that your standard of evidence now, someone somewhere committed a crime so someone somewhere else is responsible for it because of their ideological background.
I am very specific about alt right violence, the guy who killed that woman in Charlottesville was arrested and charged, name one person linked to OSF group that was charged for ANY violence? Wait, you can't, you simply 'established it'.
