Really! You tend to miss the point. Where is this wall you mentioned. As the examples illustrate, the religious content was blatant and somehow walked right through that wall you mentioned. This particular book shows that the wall was rather porous up until the twentieth century. And your denigration of Massachusetts would apply to the whole United States. Your view of history makes it seem impossible for the United States to have even come into being. I laugh in your general direction.
Wall? Did I ever mention a "wall" in my posts? Is this metaphorical? Sorry maybe I am dense but I don't recall mentioning a wall anywhere. Um... can you elaborate on what you mean?
