Intrinsic Evil

I don't know how Catholics will react or not, to the bishops use of the term "Intrinsic Evil" to describe same sex unions, called marriage by the couple and many others.  I will wait and see what kind of questions I get or responses I hear from people.  Will the response be like the one on artificial contraception back in the late 60s?  Some left, some stayed and some ignored the teaching.  Catholics tend not so much to "leave" as to stop attending worship services and participating in Church community.  I notice that Mormons seem to formally leave the church over their leaderships outlook on same sex couples.  We will see.
