Why Did San Francisco Protesters Target Basic Instinct?

Michael Douglas says Basic Instinct drew a protest from the LGBT community as soon as the production thought it was shooting the movie in San Francisco. The offense was a bisexual woman who was an ice pick killer. Douglas told the protesters that villain parts are the best parts to play. The protesters called the role a derogatory statement on a bisexual woman, and they were serious.

The production ended up shooting scenes in San Francisco with 40 SWAT officers surrounding the whole block to hold off the protests. Douglas asked how the protesters knew the plot and how they knew the script. They got hold of it. Someone linked the writer's script, which Douglas sets aside as another story.
