It was an article that implied that trans women were coercing sex from lesbians.
Now the article was based on a poor premise to start with, "Do some <people in group> do <bad thing>?" is almost always going to be "yes" because there are bad people in basically every demographic. That doesn't mean we go around writing fearmongering articles about those groups. But it gets far, far worse.
The article was based on a survey of 88 women from a group called "Get the L out", whose entire purpose is trans exclusion. So heavily sampling bias to start, to say the least. The group, and the survey, also considered things like saying that trans women are women or can be lesbians to count as "being coerced into having sex with trans women", because implying that trans women are women means that they can be lesbians means that they are within the broader dating pool of lesbians, and to them that amounts to coercing lesbians to date men. Which is obviously absurd and not what a normal person would think of when hearing "coerce into sex". So the survey was deeply misleading and not at all what the headline implied.
The second main contributor to the article was adult actress Lily Cade. Who has admitted to sexually assaulting multiple women. Which makes her an odd choice for an article about sexual assault, don't you think? These assaults were known long before the article was written, and came up with a Google search. Odd that it slipped through the BBC's rigorous editorial process. Cade also went on a rant a few days after the article was published, where she called for all trans women to be executed, and called for several named trans women to be lynched. The BBC cut her contribution with a vague message not explaining why.
The BBC also claimed to have reached out to prominent trans women who speak about sex, and claimed that nobody agreed to speak with them. Which was proven to be a lie when Chelsea Poe, a high-profile trans woman who speaks about sex and relationships, revealed that she had in fact been interviewed.
Genuinely one of the most disgustingly biased pieces of "journalism" I've ever seen.
