You are very clever to see that by calling upon the Bishops to confront racism, these people are agitating to divide people.  Modernists won't admit this, but obviously when one calls upon the Bishops to do anything that the Bishops are not doing on their own, it is agitation.  Maybe, shall we say, an attack on the church?  Sigh.  How much better off we would be if people would just accept things the way they are and do as the Bishops tell them, when the Bishops tell them.  It's the church's tradition.  It's what Jesus wanted us to do.
