If you think that these legislators are being disingenuous and are hiding a conscious aim of trying to hurt people in majority groups then perhaps we need a new term like "virtue washing", i.e. using empathy for one group to mask a harmful agenda against a different group.

I personally don't believe that most supporters of such policies are consciously motivated by a desire to harm those in majority groups, as many of these supporters are themselves in majority groups. They probably just don't think that the policies will affect them, or realise that the policies could backfire and be used against minorities.
