And the National Enquirer released a slideshow about Depp’s “bisexual bride’s lesbian past” that shows a real misunderstanding of how bisexuality works. Bisexual people don’t go from being lesbian to straight based on who they’re in a relationship with — they’re bisexual the whole time.
The actress Evan Rachel Wood, who is also bisexual, expressed some displeasure with the media coverage on Twitter. Wood quoted a tweet that said “Amber Heard‘s sexuality is only relevant in that bi women are at far greater risk of experiencing intimate partner violence. Bisexuality however is not a reason for violence. It doesn’t mean Heard is somehow immoral or deserving of abuse.” She also retweeted “What does amber being bisexual and having lesbian friends have to do with anything? F*** the media seriously..”
The first tweet has since been deleted, The Independent reported, but they make important points about how Heard’s bisexuality is being received in this context — and Wood is definitely not alone in this observation.
