PinkNews is claiming that LGB Alliance has worked with the Heritage Foundation before?

The founder Bev Jackson has said the group’s goal is to challenge gender identity. She admits that it has collaborated with right-wing groups like the Heritage Foundation that are anti-gay, anti-abortion and oppose same-sex marriage.”

All I can find is a statement from them that:

The leftwing silence on gender in the US is even worse than in the UK. This story explains why working with the Heritage Foundation is sometimes the only possible course of action. https://thepublicdiscourse.com/2019/04/50959/

...which is not an admission that LGB Alliance worked with Heritage Foundation. The story linked talks about how the author tried reaching out to mainstream media to cover detransition topics and nobody would listen, so finally she ended up asking the Heritage Foundation and they agreed to give her a platform. I think that speaks more to censorship in mainstream media than anything else... But regardless, PinkNews wants the reader to banish all thought of 'nuance' and just assume that vague, menacing-sounding associations between LGB Alliance and the Heritage Foundation are afoot. Absolutely ridiculous. The article writer who worked with the Heritage Foundation is not associated with LGB Alliance. And here they are claiming:

[Bev Jackson] admits that it has collaborated with right-wing groups like the Heritage Foundation that are anti-gay, anti-abortion and oppose same-sex marriage.

She should sue them. How is that not slander/libel?
