A bookstore in San Francisco announced earlier this month that it will no longer sell titles by J.K. Rowling, including her popular “Harry Potter” series, due to the author’s anti-transgender views and advocacy.

Booksmith, which opened in 1976 and is in the city’s Haight-Ashbury neighborhood, said the final straw came last month, when Rowling announced on social media that she would use her personal wealth to fund the J.K. Rowling Women’s Fund, which describes itself as a legal fund to support “individuals and organisations fighting to retain women’s sex-based rights in the workplace, in public life, and in protected female spaces.”

Though the fund doesn’t mention trans people specifically, Rowling has been vocally opposed to trans women’s inclusion in women’s spaces, and proponents of efforts to restrict trans rights often describe such efforts as advocating for women’s “sex-based” rights.

“With this announcement, we’ve decided to stop carrying her books,” Booksmith said in a statement on Instagram. “We don’t know exactly what her new ‘women’s fund’ will entail, but we know that we aren’t going to be a part of it. As a group of queer booklovers, we also had our adolescences shaped by wizards and elves. Look at us, it’s obvious. If you or someone you love wants to dive into the world of Harry Potter, we suggest doing so by buying used copies of these books.”
