The Weather Underground committed over a dozen bombings back in the day and the only deaths were WU members from a failed explosive. The wikipedia page has a table of right-wing terror attacks while the page for left-wing terror mostly describes guerilla groups in civil wars.

Generally no, Antifa is not a violent organization in the same way that violent white-nationalist/neonazi groups are violent.

Antifa hasn't shot up a church/synagogue/mosque. Followers of modern fascist sects have.

You're either willfully ignorant or purposefully biased to consider them on the same playing field.

“Antifa has…” is like saying “Nerds have” or “Hackers have”. It is really only a broad label, either assigned by one self or by others. I know people who are strictly against any violence and still proud to use Antifa “branding”. Others wouldn’t want to be called Antifa but are called that by others.

You are a HN user. Saying “HN users have enacted physical violence” and implying it is all of them is just utter bs.
