“The NSA and other spook agencies can type your name in and bring up every site you ever visited...”
Absolutely they can if they investigate someone, but there are over 300 million citizens in this country and they are not all being investigated to find their religion and put it on a list. (Since we have a family member who works in investigation at the NSA, he already knows we are Catholics and so is he.)
How many keystrokes do you think it takes for someone at NSA to bring up a list of every Pentecostal who owns a gun and visits FR? That is my point. They already have a registry of every Muslim in the country.
