Maybe say it opresses people of color? Other than that this is exactly what id do. Maybe also use sonething that the LGBT+ community has the same rights and will be left defensless against hatecrimes.I'd honestly go further. "If you vote for this, you hate black people. Why? Black people have been under assault by law enforcement and government as we saw with George Floyd. A lot of you claim to be allied in wanting change. But voting for this, you take those very people you claim to ally with and put them on a list controlled by the police.
Does an ally do that? No. Someone who hates black people does."
If you're unwilling to use the left's playbook and take it to another level, there's no chance of moving the needle. Sucks, but it is what it is.
