<p>1) People who call themselves bananas are clearly not bananas. That’s the point. You’re interpreting religion as merely a self-identification. But it might as well not exist if it has no effect on the life of the individual at all. Unless you consider a campus of self-proclaimed fruit to be exactly that. The assumption of their faith is entirely inconsequential as long as it has no impact on the rest of the campus in any way whatsoever. The assumption that a student will self-identify as a banana hardly means that campus is full of them, unless the students are tall, yellow, and protected by a soft shell.</p>
<p>2) In light of that distinction, I have not done enough research to determine the answer. </p>
<p>3) Clearly you are unaware of the number of people who claim to be religious based solely on their upbringing and not any actual beliefs or actions. So that distinction is not at all absurd.</p>
