Just since 2016, the GOP has done, tried to, or promised to:
- institute voter ID laws in three separate states (TX, WI, NC) that were struck down (by red state judges, yet!) for --you guessed it-- deliberately targeting minorities
- ban Muslims from certain countries from being allowed to enter the US
- STILL say gay marriage is wrong and should be overturned
- kick trans people out of the military because reasons
Republicans are the ones creating policy and law based on people's race, religion and sexual orientation. You know, their identities. All Democrats are doing is saying "knock it off".
The GOP is the party of identity politics. They just never target the identity of straight white people so Republicans don't care.
