"How many Catholics truly CARE what these guys say on human sexuality anymore?"

Regarding a subject as laden with moral content as sexuality, the problem is that you have it completely backwards.  You haven't been listening to the Bishops for decades.  And now look at our mess:  scores of millions of aborted babies, what a horror; the near destruction of marriage; children without fathers (even among upper middle-class "liberated" women, the thought is, "Who needs a man to help raise a child?"); gay marriage; transgenderism --- all advocated by the weirdest bunch of people mankind has known since Rome year A.D. 1.   And you think this is good.  Lost.
