The 2004 Perrier Award nominee, who returns to the Edinburgh Festival this year, was asked by Stylist if comedy needs feminism.
"There's a whole generation of women who don't care about feminism," she said.
"A lot of younger women think 'lezzing off' for the boys is equal rights. It's not!"
She added: "Little girls are obsessed with Katy Perry. Her videos are full of phallic symbolism; liquid shooting out of tubes, lollipops, hairbrushes by the mouth. It all looks very BJ..."
Asked how often the 'are women funny' debate is brought up with her, she replied: "Constantly. Would you ask if a Chinese person was funny?
"Would you feel comfortable asking this about any other group in society? Because it's pretty offensive..."
Sarah Kendall performs her Get Up, Stand-Up set at Pleasance Courtyard until August 27. Tickets are £11 and are available now.
