Part 2
E2, on the other hand, appears to me to be an alliance of "elements of Catholicism" with "elements of fundamentalism" based on shared certainty about values of rejection, of opposition, of rejection of socially controversial, disputed moral propositions. It is at its core an alliance of convenience against others. The movement does not envisage rapprochement  among its members; rather both sides agree not to acknowledge or face or confront what they actually feel about each other. The Catholic element (conservative Catholics) do not relinquish for one moment their rejection of the core beliefs of the Fundamentalist element; and vice versa. Of particular importance in assessing E2 from a Catholic perspective is that a very significant portion of fellow Catholics (progressive, liberals) are as much the target of E2 rejection and enmity as a subset of secular ideologies. Not sure, but suspect something similar is the case on the other side. Therefore, E2 is not Church to Church.
