As Boston braces for a Free Speech rally that many fear will attract white supremacy agitators, the National Director of the Knights of the Ku Klux Klan reports that some Massachusetts members plan to attend.

Organizers of the Saturday rally, including 23-year-old Framingham University student John Medlar, say the "Boston Free Speech" group is solely focused on highlighting each person's right to the first amendment.

"We categorically oppose groups like the Nazis, KKK and so forth," Medlar told MassLive.

"As private citizens, part of free speech is the right of free association. We have the right of who we want to share our platform with," he continued. "If they do show up, we will separate them from us. We will exercise our right of free association, and disassociate ourselves from them."

Despite promoting a message of non-hate, the rally around first amendment rights appears to be a magnet for racist and white supremacist groups.

National Director of the KKK Thomas Robb told the Boston Herald that members from the Western Massachusetts are planning to attend the rally on Saturday, and he believes members from the Greater Boston area will also attend.

"I don't think they're going to cause a disturbance," Robb told the Herald. "Our members don't stand out, they don't walk around giving Nazi salutes, they might be your next door neighbor or Cub Scout leader."

On Wednesday, the Boston Parks and Recreation Department granted John Medlar a permit to rally at the Parkman Bandstand on Saturday from noon to 2 p.m. The free speech advocates, and any white supremacists that join them, are expected to be met with a large counter-rally advocating against supremacists like the KKK.

A separate rally, titled "Fight Supremacy! Boston Counter-Protest & Resistance" on Facebook, says marchers plan to meet in front of the Reggie Lewis Athletic Center at 10 a.m. before marching to Boston Commons "to demand justice and stand in defiance of white supremacy." The event plans to rally for "Black Lives, LGBTQI Lives, Indigenous Lives, Palestinian Lives, Cape Verde Lives, Latinx Lives, Jewish Lives, and all who are marginalized," according to the Facebook page.

Boston Police Commissioner William Evans said officers will be out patrolling the event, as they do with any major protest. The commissioner has also reportedly said that anyone that becomes remotely violent will be placed in a holding cell, according to the Boston Globe.

Police have asked rally-goers to keep backpacks, strollers, bikes, weapons and pets at home. They also ask that no one brings signs attached to sticks.
