That rally saw a woman killed after an avowed white supremacist rammed his vehicle into a group of anti-racism counter-protesters.
Amid National political unrest, a right-wing group called "Patriot Prayer" set their sites on San Francisco for a protest and rally at Crissy Field that never ended up happening Saturday.
The goal of holding the rally, Gibson has said, was to challenge people on the left and the right who are too intolerant of any viewpoints that don't match their own.
"... We still have to prepare for contingencies."
The anti-Trump organization By Any Means Necessary, which has sometimes supported violent tactics, had vowed to shut down the Berkeley rally even before it gained new prominence with the cancellation of Gibson's event. Patriot Prayer's news conference is scheduled there later in the day.
"San Francisco as a whole, we are a liberal city and this is not a place for hate or any sort of bigotry of any kind", Bianca Harris said.
Across the bay, Berkeley Mayor Jesse Arreguin said he planned to attend a counterprotest Sunday organized by almost 60 community groups. Earlier Friday and Satruday, officials erected fencing and a large contingent of police monitored Alamo Square park, where the group Patriot Prayer was set to hold its event - but no one ever showed up.More news: Newborn found, 2 arrested in Fargo woman's disappearance

Several groups have reportedly organized counter-demonstrations on Friday and Saturday during the permitted rally.
"Do not engage with the members of this group, whose only priority is to incite violence through divisive rhetoric, so as to avoid dignifying their display of hatred", Lee said.
Joey Gibson, in a Facebook Live broadcast Friday afternoon announcing his decision to call off the "free speech rally", said the event at Crissy Field, a part of the Golden Gate National Recreation Area, could be "a trap".
This weekend's controversial far-right protests, slated to be held on both ends of the Bay, have been canceled-each citing violence for the sudden change of plans.
Small groups of activists and counter-protesters on Saturday were marching the streets of San Francisco and deciding on new gathering points after a far-right rally at Crissy Field was scrapped. "I think it's a really powerful message that we're sending to people who come here to try to spew messages of hate that it's just not welcome in this city".
The weekend's events kicked off on Friday with a Unite Against Hate rally at the San Francisco Civic Center.
Organizer Amber Cummings said in a lengthy statement issued via Facebook that she had "grave concerns for the safety of the people attending my event".
Organizers of the Patriot Prayer rally blamed "Antifa Punks" for Saturday's canceled rally. With a counter rally at nearby City Hall, he predicted violence in residential neighborhoods surrounding the park.
