Taylor Swift recently spoke about her stance on feminism, saying “Misogyny is ingrained in people from the time they are born”.

She told Maxim, “Honestly, I didn’t have an accurate definition of feminism when I was younger. I didn’t quite see all the ways that feminism is vital to growing up in the world we live in. I think that when I used to say, ‘Oh, feminism’s not really on my radar,’ it was because when I was just seen as a kid, I wasn’t as threatening. I didn’t see myself being held back until I was a woman. Or the double standards in headlines, the double standards in the way stories are told, the double standards in the way things are perceived. A man writing about his feelings from a vulnerable place is brave; a woman writing about her feelings from a vulnerable place is oversharing or whining.”
