Sure but you are sticking your head in the sand if you think that that doesn't accurately represent the religious angle of people. If their data says they are interested in the bible, christianity, prayer groups, or whatever, what's more likely, that they are intellectually curious and just doing research? Or that they are just christian?
That's like newspapers running articles saying so-and-so is charged with the rape of whats-her-name. Even if he's later found innocent, he still felt the repercussions. So, where do you draw the line?
More importantly: what's the problem with the data they are presenting? I see no problem ethically or legally, though I'm sure some might feel uncomfortable with the amount of information they've willingly, if unknowingly, shared.
