I don’t think these issues are being ignored but a two seat majority in the Senate, comprised of red state democrats, does limit the ability to do anything here. If you look at the state level there is a lot happening to address a variety of issues by blue states. Red states are moving backward
Ignored might be a strong word, but, especially on the national stage, there hasn't been the impetus to make strong strides on minority rights for a while. Part of that is the fault of a certain proportion of Democratic voters, and part of that is the fault of Democratic politicians (and all of the blame, of course, lays twice as heavy on the GOP), but it is definitely a continuing problem.
