A giant canvas pink triangle has been placed in the hills of San Francisco Volunteers said they are taking a stand for their rights amid a national pushback from anti-LGBT Republican lawmakers.

Hundreds of volunteers installed the triangle made out of cloth and canvas on San Francisco’s Twin Peaks viewpoint, one of the city’s most popular tourist spots, as part of the city’s Pride celebrations.

At nearly an acre in size and visible from up to 20 miles (32 kilometers) away, this year’s triangle is the largest since the annual tradition started in 1995.

“We’ve had a lot of progress in the last decade: Since we had so many victories, people are coming out of the woodwork to push us back.

Patrick Carney, co-founder of Friends of the Pink Triangle

The pink triangle is a symbol that has become associated with the persecution of homosexuals during the Nazi regime in Germany. As part of their campaign against homosexuality, the Nazis implemented various measures to identify and persecute gay men. They established a special police division known as the Reich Central Office for the Combating of Homosexuality and Abortion. This division actively sought out gay men and compiled lists of individuals suspected of homosexuality.

In concentration camps, where millions of people were imprisoned and killed, including Jews, political dissidents, and other marginalized groups, the pink triangle was used as a distinctive badge to identify male prisoners accused of homosexuality. It is important to note that lesbians were not specifically targeted in the same manner, and women wearing the pink triangle were usually those considered “asocial” or “anti-social” rather than solely due to their sexual orientation.

Organizers said recent legislation that has sought to limit their rights, including Florida’s so-called “Don’t Say Gay” law banning classroom instruction about sexual orientation, make the pink triangle especially relevant this year.
