I think this is the point of this tweet?

In the Senate, Vance introduced a ban on gender-affirming care for minors called the Protect Children’s Innocence Act. “The act includes an array of far-right, anti-transgender buzzwords and ‘bans’ a variety of medical procedures, none of which are a part of transgender healthcare for minors,” GLAAD notes. Violation would be a Class C felony, and conviction would come with a prison term of 3.5 to 15 years. The bill has not passed. He also infamously said Democrats want to bring immigrants into the U.S. to turn them transgender.

In 2022, he tweeted, “I’ll stop calling people ‘groomers’ when they stop freaking out about bills that prevent the sexualization of my children.” He has also “repeated false rhetoric to inaccurately claim that bills censoring classroom conversation about LGBTQ people are about ‘parents’ rights,’” GLAAD reports.

He has stated that he does not believe antidiscrimination laws should cover sexual orientation and gender identity. When running for Senate, he criticized his Democratic opponent, Tim Ryan, for voting for the Equality Act, a national ban on anti-LGBTQ+ discrimination, as a member of the U.S. House. The act has yet to pass into law.
