Pointedly, KB ends his article, "Religious rights include Christian rights ... but must encompass more than the version of Christian rights defined by earlier times when inimical social mores brushed aside the Sermon on the Mount."  Many Christian would like to excise the Sermon on the Mount.  A singular departure from Judaism.  Many Christians are more comfortable w. Judaism than this departure from old thinking, acting. 
Interesting, the Sermon on the Mount is a central focus of the Amish & those of the Anabaptist tradition.  They seek to personally witness to their belief without expecting others to conform to their practices. They do not look to the state to enforce their interpretations. Too bad more Christians don't emulate them.  How many Christians communities could respond to mass murders as the Amish response at West Nichol Mines massacred on 10/2/2016?  They walked the walk as to what the Sermon on the Mount is in deed.
