"One reason for the discrepancy is the far right’s efforts to recruit veterans and service members to their cause, said Josh Lipowsky, a researcher with the Counter Extremism Project who authored a report last year about far-left extremism. Lipowsky determined that today’s far-left groups lack the organizational structure used by the far right.

The Patriot Front, a white nationalist and neo-fascist hate group, takes applications from prospective members, many of whom claim to have ties to the military. Far-left movements tend to comprise more broad ideological positions rather than forming into specific groups with such bureaucratic entrance procedures, Lipowsky said."
