I'm not sure what you mean. Republicans don't have a platform for addressing issues such as inequality, racism, criminal justice reform, gerrymandering, global warming, etc. They either deny that the problems exist or advocate the same policies that they have for decades.
Republicans have been playing a leading role on criminal justice reform, actually. Some of the earliest voices pushing for it were conservative ones, well before there even was such a thing as a BLM movement. The fact that Dems and progressives more generally will never acknowledge this suggests that their commitment to genuine social justice is rather shallow. Biden and Harris were both known as proponents of failing "tough on crime" policies until very recently, when they basically flip-flopped on the issue with zero explanation or public self-criticism of their previous stances. Riding the BLM bandwagon, nothing more than that.
Republicans definitely deserve credit for the work they have done on criminal justice reform. The law he signed is about the only thing that I think Trump did right.
