Yes, the opportunists in this parasitical movement are causing insult and injury to gay men and lesbians by appropriating, cannibalizing and rewriting gay and lesbian history to make it appear as though gay and lesbian culture and civil right organizing have always been about and for people with same-gender attraction rather than same-sex attraction. Because so many people in this movement have cluster B personality traits or disorders including high rates of narcissism, they're also rewriting history to make it appear as though most notable gay and lesbian figures of the past like Pauli Murray were "trans" or "non-binary" - and that "trans" people were always at the forefront and center of gay and lesbian political organizing.
But even worse, trans activists have long been waging outright war against lesbians, trying to invade and destroy lesbian events and communities in the name of "inclusion." This is because the vast majority of "trans women" today are heterosexual males who see bedding lesbians as the ultimate validation of their gender identities and the way to wreak revenge on women have no sexual interest in males. Just look how they sought to destroy MichFest, the USA's now-defunct major lesbian event, and the concept of "the cotton ceiling."
Also, check out the case of Dana Rivers, a "transwoman" pending trial for brutally murdering a lesbian couple in Oakland CA and their teenage son. Those who've looked into the case in depth say that Rivers was sexually obsessed with and stalking one of the women Rivers allegedly killed.
Due to the mushrooming numbers of tween and teen girls coming out as "trans," now gay men are finding they are under the same sort of threat from heterosexual females who "identify as" gay men that lesbians have been dealing with for decades due to all the heterosexual men who "identify as" women and call themselves lesbians or transbians.
Also, it hasn't escaped notice that the push to "transition" children and adolescents seems motivated by a whole lot of homophobia and will inevitably have the effect of reducing the numbers of well-adjusted, self-accepting, out and proud gay and lesbian adults.
