<<You must have missed the part where it was a tiny cross, only visisble to someone who had to look really closely. >>
No, but you must have missed another chunk of real life, bringing your experience of it down to maybe 2% of your total waking hours. In real life, once you know that a design includes a particular design element, no matter how small it is, when you see the design, you know that the design element is there too.
Oh, and surprise!! both Jews and Muslims also believe in angels. So there's nothing particularly Christian in that concept. Christians didn't even invent the idea - - they lifted it from the Jews.
For your future information, the words "Los" and "Las" are the masculine and feminine plural forms of the English word "The," so there is nothing at all Catholic about them. "Las Vegas," for example, means simply "The Meadows." "Los Alamos," "The Poplars." Unless the Catholics are nature-worshipers, there is nothing particularly Catholic in either of those names.
"San" and "Santa" are of course indicative of sainthood. San Francisco for example is named after St. Francis. Santa Catarina, St. Catherine. I think whenever a city is named for a person, that person had some kind of religion. You might as well argue that Washington D.C. is a Protestant religious name because George Washington was a Protestant.
Your arguments are getting beyond silly, but I understand. Desperation can do funny things to a man's power of reasoning.
