The May Day march Sunday in Oakland was all about the issues — there wasn’t a representative of any issue that didn’t show up.

Close to 1,000 people waved signs, banged drums, wafted incense, chanted, speechified, blocked streets and generally marched in the Fruitvale district to raise awareness for everything from workers, housing and immigrant rights to the danger of presidential candidate Donald Trump.

“We’re here to fight for equal rights and equal pay and to fight against all forms of social injustice,” said Theo Domingo, 27, as he displayed a sign urging people to “Vote 4 Trump in getting his ass kicked.”

Domingo, who meant it both literally and figuratively, explained how seeing Trump at the California Republican convention stirred him up.

“I (used to think) he was cool, but now he’s chastising Muslim and Mexican people,” he said. “That really got me pissed off.”

Also demonstrating were members of the protest group Black Lives Matter, the Oakland Workers Collective and several self-professed communist organizations, including the Progressive Labor Party, whose members were reminding observers about how they reinvigorated mundane May Day marches in the 1970s.

In San Francisco, hundreds of workers with the International Longshore & Warehouse Union marched along Fisherman’s Wharf in support of immigrant workers’ rights and to demand justice for people of color shot by police.

In Oakland, there were folks carrying Palestinian flags, people wearing Cesar Chavez T-shirts and traditional Aztec dancers banging drums and burning incense.

The marchers, including all ages, met in the Fruitvale Plaza area of Oakland, where they were inspired by speakers on a flatbed truck who led the crowd in chants.

Dozens of police officers blocked traffic in the area and attempted to manage the crowd, which by midafternoon had moved onto 35th Avenue and International Boulevard, which was briefly blocked. Oakland police urged motorists to avoid the area, but no arrests were reported.

The march meandered peacefully through the Fruitvale district and ended in San Antonio Park a little after 3 p.m.

Marcher Chelsea Charlea said her piñata depicting Oakland Mayor Libby Schaaf’s head with an electrode in the brain could come in handy if people start getting antsy as the night rolls on.

“Her brain is controlled by money and by profit,” Charlea said. “People are going to smash it later to get their feelings out.”
