Congressional Republicans introduced a measure Tuesday that would prohibit federal money from being used to teach children under 10 about LGBTQ issues.

The bill would prohibit the use of federal funds to teach children about “sexually-oriented material” as well as “any topic involving gender identity, gender dysphoria, transgenderism, sexual orientation, or related subjects”. The effects of such a law, if enacted, would be far-reaching since a range of institutions – schools, libraries, among them – receive public money.

The bill also gives parents the ability to sue in federal court if their child is exposed to the barred material that is funded “in whole or in part” by federal funds.

The bill was introduced by Mike Johnson, a Louisiana Republican, and 32 other GOP members of Congress.

“The Democrat party and their cultural allies are on a misguided crusade to immerse young children in sexual imagery and radical gender ideology,” he said in a statement. “This commonsense bill is straightforward. No federal tax dollars should go to any federal, state, or local government agencies, or private organizations that intentionally expose children under 10 years of age to sexually explicit material.”

The bill is unlikely to become law while Democrats control the US senate and White House, but it underscores how Republicans have zeroed in on anti-LGBTQ issues as a way of rallying their base.

Earlier this year Florida’s governor, Ron DeSantis, signed a law that barred schools from teaching about sexual orientation or gender identity until third grade, “or in a manner that is not age-appropriate or developmentally appropriate for students in accordance with state standards”.

More than a dozen states introduced so-called “don’t say gay” bills this year.

Republicans have also targeted drag shows as part of this anti-LGBTQ effort. Idaho lawmakers will reportedly consider a measure to ban drag shows in public.
