Yeah, they're being arrested because they're good people without a dangerous agenda
Data stands in stark contrast to claims by Donald Trump, who has argued that leftwing violence is a major threat

If you read through Foreign Policy, Brookings Institution briefs, and other legitimate analyses of the domestic terrorism situation in the United States, right-wing extremism is by far deemed to be a greater threat, with left-wing terrorism given nary a mention. This is because in *legitimate policy circles* outside of the media echo chambers, it is very clear that left wingers present little real threat to safety or democracy for numerous reasons. The right is armed, ideologically more cohesive, looking for a tipping point at which they can feel the flag has been waves to engage in violence, and orgamized. The more fringe left is a bunch of people that want to punch Nazis and occasionally tag a target, with minimal to no organization, no ideological center, little armament, and no cause that could be triggered by a single event which could result in mass violence due to their ideological incohesiveness. Comparing the two is like comparing hand grenades to firecrackers, it's legitimately stupid to anyone in the know.
With regard to your antifascist boogeyman:
As Trump rails against ‘far-left’ fascism, new database shows leftwing attacks have left far fewer people dead than violence by rightwing extremists
