I hate the realpolitik of this perspective but BF from what I know is still pretty socially conservative. There was a study done a while ago there saying something like only 8% of people would "accept a homosexual as a neighbour". Regardless of what Traore thinks it may just not be politically feasible for him to retain support from broad swathes of his coalition if he comes out swinging for LGBT rights in BF, and if his mandate collapses or his allies turn against him shit could get bad for him pretty fast.
