Should these sexually suggestive jokes be kept or deleted?

Is there a way to discuss the correctness of the proof of the RH by Atiyah in MO?

I will take a different viewpoint than some and say that the correctness of the proof can be discussed, and maybe it should. But as to how, that's a question of tactfulness and precision. When ...

Why was this question asking non-trivial examples of closed subschemes closed?

Your question was: "I would like to know examples of closed subschemes of $X$ other than $Z_n$", and when examples were given in the comments, you rejected them as trivial. Rather than explaining ...

Why has the question "Optical methods for number theory?" been closed?

Actually such devices were at one point in the 20th century the state of the art for doing certain number-theoretical calculations, notably factoring. See http://en.wikipedia.org/wiki/Lehmer_sieve (...
