"Opus Dei doesn't decree or have a politics. Its "agenda" is focused on helping ordinary Christians pursue personal holiness and apostolate in the world (less focus on the parish): How are we drawing closer to God in our ordinary day, how are we helping God by bringing souls closer to His love, etc.
It doesn't do protests and make nice flashy banners."

Really, R.D.?  Because Opus Dei doesn't do open protests, even though its members appear to be very angry in cyberspace, no one else should be allowed to protest in public?   Your understanding of the First Amendment is sadly lacking.
