The organizers of a solidarity fair at Central Park in Corvallis found the area had been chalked with offensive graffiti when they arrived on Saturday.
The social justice activists quickly went to work removing the chalk, which contained messages such as "A future for white children," said fair organizer Lisa Gonzales.
"It's a message to intimidate us," she said. "There's a lot of permission right now to express those kinds of views."
During the fair, Jimmy Marr parked his truck just outside the park and played the bagpipes. His truck bore the message "Unjew."
Marr told a reporter he was there as a demonstrator. Other men were carrying signs that said "Open borders for Israel" and "End Israeli apartheid."
"I'm here because there's bound to be people who are tangentially interested," Marr said.
Gonzales called police to the park, but Sgt. Ryan Eaton said Marr was not breaking the law by playing the bagpipes. Eaton said police had been notified of the graffiti but that it was not being investigated at this time.
Marr has previously been arrested for disorderly conduct after blasting offensive speech from a loudspeaker during a Stop Hate! rally in Springfield.
Saturday's event was the sixth annual solidarity fair in Corvallis. Gonzales and others created the event to celebrate International Workers' Day. The fair has expanded to include local social justice and grass roots groups. More than a dozen organizations were present Saturday, including the NAACP Corvallis Branch, Corvallis Sustainability Coalition, a group opposing the death penalty, Oregon Public Employees Union and others.
"A better world is possible and this is how you do it," Gonzales said.
She said the fair allows such groups to network and work together on social justice causes. Organizers moderated conversations on how to organize and led an open mic session.
Gonzales said there appears to be increased energy in organizing and activism since Donald Trump was elected as president.
"In today's day and age, there are more organizations coming together to respond to the current political environment, said John Friedlander, communications coordinator for the NAACP Corvallis Branch.
Froggi VanRiper, a team member for YouCAN Corvallis, was collecting signatures at the fair in support of a proposed city ordinance to reduce greenhouse gas emissions.
"Climate change is an issue that knows no geographical boundaries," VanRiper said. "It knows no political boundaries."
