The Economist has a straight-forward piece explaining the issues in the public university case before SCOTUS where a Christian Group is challenging university policy which forces the group to accept unrepentant gays into membership. And then there is the suit by the three bisexual baseball players who claim the Gay World Series discriminated against them.

We find that players have up to 4% fewer fouls called against them and score up to 21⁄2% more points on nights in which their race matches that of the refereeing crew. Player statistics that one might think are unaffected by referee behavior are uncorrelated with referee race. The bias in foul- calling is large enough that the probability of a team winning is noticeably affected by the racial composition of the refereeing crew assigned to the game.
