A double standard for Black athletes following Kamila Valieva and Sha'Carri Richardson

Can we get a solid answer on the difference" between their situations? Mediators ruled that Valieva should be allowed to skate regardless of testing positive for performing enhancing drugs.  While suspending Richardson for Marijuana use used to cope with depression and grief.  How do we address the double standard within the athletic community as well as the Black community?  Do we as people of color have a responsibility to uphold higher standards or does that higher standard actually backfire and shrink the voice we have?
