Even the in lowest, low Church Anglican parish, chances are there is an altar rail, whereas the most Catholic churches have ripped them out. Of course, the Anglican church copied the Catholic one since the Anglicans broke off from the Catholics. 

Why should anyone be ashamed to kneel to recieve Our Lord?  How do you reckon it is some kind of superstition?

Still, how Orthodox and Eastern Catholics can have a full on iconostasis and that is fine, whereas a two foot tall rail that does not impede view of the sanctuary is unacceptable as a "barrier" boggles the mind.  The East is seen as "exotic" so they get a pass, but members of the second largest gathering of Christians are aghast at some of the things that go on in your typical Novus Ordo.
