I'm a lesbian and I mentally parted company with Stonewall and began opposing it and a lot of other LGB organisations when they added the T and then the Q and then all the other identity letters to the original LGB.
LGB people are united by same-sex attraction. TQ and whatever are linked by their insistence on identity — defining themselves by feelings or whatever. LGB people are united by their experience of homophobia. Transgenderism, and its attack on sex, is inherently homophobic. The two cannot and could never exist comfortably together. As soon as Stonewall added the T to their constituency, it began working against its core community.
Stonewall and other organisations have done this by force. Uncoupling the LGB from the TQ+ is one of the most important things anyone with a GC stance can do.
Please, let us work towards making the letters LGBTQ+ a badge of ignorance and shame, not something that employers should be plastering everywhere as proof of how progressive they are.
