To my engineering mind, I see this as an asymptote. (Which is typically accepted to never actually reach the asymptotic value, but gets 'close enough' for physicists.)
In this case it's a function of dividing by 10 and adding to the summation. The function is asymptotic to 1. To me, asymptotic to 1 and equal to 1 are different, but not for any practical purpose.

Censorship by definition. Whether it's warranted or not is a different question. It's sad that a well known literary reference like this is either unrecognized or discriminated against though. Had his shirt had a huge cross or a fish symbol he wouldn't be experiencing this problem. Moreover, his shirt is a statement about his rights, not about the existence of a deity. It's thought provoking. It seems that any time a free thinking teenager has the audacity to speak their mind, they're quickly crushed by people in the system who have long since given up the habit of thinking for themselves.
