As with everything with the TRA lobby, facts are embellished, claims about being wiped from existence are made.
It's not a "don't say gay" bill, it's an age appropriate sex education bill. It's about how you frame it, the equivalent is the Family Sex Show, which because LGBT lobbying groups didn't get the first opportunity to frame the argument was rightly seen as having material completely unsuitable for children. If the lobby groups got in first, then the argument would be about "bigots trying to ban a play teaching children about equality and preventing people from acknowledging LGBT people".
