In their latest book, “Just Action: How to Challenge Segregation Enacted Under the Color of Law,” Leah Rothstein and her father, Richard Rothstein, explore the myriad ways in which community groups can work to address residential segregation. On Saturday, Oct. 7, Ms. Rothstein will come to the Dance Palace to discuss her new book and speak with Point Reyes Station activist Mary Morgan. “When I started writing this book with my dad, I wasn’t sure we would come up with enough solutions,” Ms. Rothstein said. “But in the research, we discovered there’s so much to be done on the local level. The federal government created the segregation, but it is perpetuated by local policies and practices. We give an example of a community in every type of activism. There’s no one answer that’s going to undo the whole tapestry. It’s a puzzle that has a lot of pieces, and there are communities tackling these pieces across the country.” The book follows up on Mr. Rothstein’s New York Times Best Seller, “The Color of Law,” which lays out the history of state-sponsored segregation and the racially biased policies implemented by most presidents in the pre-civil rights era. Written in the wake of Black Lives Matter, the Rothsteins’ new book provides examples of tangible, non-performative change that address obstacles like zoning laws that act as a continuation of racist home deeds. In Marin, though most redlining spanned the 101 corridor, neighborhoods like Seadrift, Bolinas’s Big Mesa, and parts of Woodacre are riddled with these deeds. A county project launched in 2021 is hoping to modify racially restrictive covenants. The initiative urges owners of pre-1970 homes to identify discriminatory language in their real estate documents, report it, and have the county issue a certified document nullifying the restrictions for future buyers. “Zoning has been used across Marin, the Bay Area and the country in expensive areas to make sure only one family lives on a property,” Ms. Rothstein said. “Racist deeds are not unique to Marin, but one interesting thing Marin has done is give homeowners an option to staple a statement on top of racist deeds. We think it’s important not to completely erase history. If we don’t grapple with how we came to be segregated, we can’t recognize how to get past it.” Ms. Morgan interviewed Ms. Rothstein in May for Indivisible West Marin’s radio show, “The Low Down.” Afterwards, the Mainstreet Moms pushed for an event at the community center. Ms. Morgan said systemic racism and housing segregation are often overlooked when considering affordable housing solutions. “A great deal of West Marin is populated by older, white, wealthier people,” she said. “The influx of VRBOs has made that even more difficult, because it takes housing out of the housing stock for rentals. It’s not just a question of building more housing, but it depends upon where that housing is located. Building affordable housing in Marin City or the Canal District, where there’s already density and segregation, exacerbates the problem and does nothing to mitigate it.” Free tickets are available at https://www.eventbrite.com/e/leah-rothstein-tickets-691992166197?aff=erelexpmlt.
