I think what riverbashing was saying was that if a particular temple wanted to restricted access it could. I think that here in the US a church/etc can do the same thing using a 'private property' law of some sort. Something to the effect of "It's our private property and we don't want <whomever> here" That said, most religious groups that I've seen (in the US) try to welcome potential new members and have (like you said) welcomed visitors as well.
