Pushing a socialist agenda and saying they fear a Trump administration, thousands of demonstrators are expected to take to the Common tomorrow night to protest the inauguration.

Eight activist groups under the umbrella of “Socialist Alternative” have dubbed the event “Occupy Inauguration.” Their issues include:

• Making Boston a sanctuary city while stopping deportations of illegal immigrants.

• Stopping mass incarceration of minorities.

• Legislating gay and transgender rights.

• Taxing the “super-rich like Trump” to fund universal health care and free college tuition.

“I’m personally afraid of his presidency,” said Keely Mullen, 22, of Roxbury, one of the organizers. “One of the things that will counteract the fear is what is likely to be mass demonstrations all across the country. … Trump doesn’t have a mandate — he didn’t win the popular vote.”

Mullen, a member of Socialist Alternative, said it’s important to stage protests around the country as well as in Washington on Inauguration Day.

“It’s not just in D.C. that people are resisting Trump, there are protests all over the place. We are seeking to strengthen the roots that we have in the city,” she said.

As of yesterday afternoon, 2,200 people had indicated on the event’s Facebook page that they plan to attend while another 7,700 have said they might attend.

Other groups that are listed as co-sponsors include Massachusetts Peace Action, Boston Feminists for Liberation, Boston Democratic Socialists of America and Socialist Students.

The demonstrators say they will meet at the Parkman Bandstand at 6 p.m., march to the State House, around Beacon Hill and then end at City Hall.

Boston police said yesterday all groups involved obtained required permits. Cops will utilize “additional police resources” but said they don’t expect any problems and urge demonstrators to use public transportation to avoid tying up traffic.

Joe Sugrue, 21 of Allston, a member of two groups participating, said large-scale protests have “proven themselves to be effective tools in fighting against marginalization, discrimination and other forms of oppression people endure under capitalism and will certainly endure under the Trump administration.”
