US has a special definition for what constitutes "left" that doesn't apply outside. Compared to European leftists, US leftists are center-right.

Charlie Kirk was shot by a center-right guy on September 10, 2025?

Luigi Mangione shot the UnitedHealthcare CEO December 4, 2024 and had an anti-capitalist manifesto, was he center right?

What about Elias Rodriguez (leftist activist, Israeli Embassy Staff Shooting)?

Michael Reinoehl (antifa) who shot Aaron Danielson?

"No Kings" Vance Boelter who shot two politicians?

"Anti-ICE" Joshua Jahn who killed two detainees and wounding an agent in the Dallas ICE Facility Sniper Attack?

US leftists are the same murderous closeted communists as they are everywhere else.

They assassinate people (see recent cases), perform terrorist attacks (peaking at ~500 (!) bombings in 1971), form mobs to socially ostracise people they don't agree with, distribute brazen propaganda in mass media and subvert every organisation they join.
