The petition explains that Antifa engages in terrorism — “the use of violence and intimidation in pursuit of political aims” — and thus should be declared a terrorist organization.
The left-wing anti-capitalist political movement styles itself a fighting force against "fascism" and "Nazism," justifying action — including violence — against anyone whom they claim fall into such categories; this has been proven to include essentially anyone on the Right, even if they are active participants in combating neo-Nazism on the so-called "alt-right."
Antifa has become increasingly active in the past two years, attempting to or succeeding in shutting down speeches from right-wing or liberal speakers by triggering a heckler's veto. Last weekend, Antifa appeared in Charlottesville to "punch Nazis" at a rally-turned-riot where a man with white supremacist ties murdered 32-year-old Heather Heyer by driving a vehicle into a crowd of counter-protesters.
The group also participated in violent acts against police officers and free speech rally participants in Boston on Saturday, attacking cops and tossing bottles filled with urine at groups of law enforcement.
"AntiFa has earned this title due to its violent actions in multiple cities and their influence in the killings of multiple police officers throughout the United States," reads the petition. "It is time for the pentagon to be consistent in its actions — and just as they rightfully declared ISIS a terror group, they must declare AntiFa a terror group — on the grounds of principle, integrity, morality, and safety."
As noted by The Daily Caller, the petition is posted on a governmental website created under the Obama Administration called "We the People" which mandates the White House to give a formal response within 30 days if the petition gains 100,000 signatures.
