They help LGBTQ+ youth get therapy. They are anti-conversion therapy, the act of trying to "fix" someones gender and/or sexuality.
Another way to help the problem is to not perchance from companies who give money to anti-gay or anti-trans organizations. Such as Chick-Fil-A. You could stop buying from Disney as they canceled a show because it "Didn't fit the brand" after the main character got in a queer relationship and still made a "There's room for everyone under the rainbow" post in June. Creators who have worked with Disney have told stories of the censors telling them to get rid of queer parts of their show. "Best Buy donated $100,000 to Tom Emmer, a socially conservative Minnesota gubernatorial candidate with very contentious opinions. In addition to his anti-gay stance, Emmer supported castration of sex offenders, banning abortion entirely, and the pharmacists’ rights to deny contraception"(NYU local).
