The "trend" you denigratingly refer to is the second Vatican Council.  Meanwhile, another "trend" was wreaking havoc on/in America, the Vietnam War, which was based on a lie (Tongkin Bay) - a "trend" which, as Ken Burns and Lynn Novick show in their currently airing documentary, is a major cause of America's mayhem which grows worse by the day right up to today.  Americhristianity has its source in the division sparked by the Vietnam War and the protest movements against it.  It is a cult masking as "Christian" in which all of America's ugly traits, personified in Trump, whom WE elected, and who is the latest emanation of America's self-damaging refusal to come to terms with the reality of its own house divided.  Rather than undertake the painful but healing Self-Examination, it is easier to flee from it with the call for a Leader, the Gun, and a cross draped in the flag (white supremacist ultra-nationalism).  THIS is the "trend" which is the reality today. America grates itself kaput.
