I provided an answer (whether it really is one or not is a matter of dispute) to the following question: Where does the proof for commutative rings break down in the non-commutative ring when showing only two ideals implies the ring is a field?
My answer was deleted on the grounds that it does not answer the question. So far so good. Now how come that there is another "answer" (the one with the Weyl algebra) which also does not answer the question (which is "where does the proof for commutative rings break down in the non-commutative ring?"). In fact it is rather obvious that my answer (or comment or whatever) is certainly more relevant than the one with the Weyl algebra. (If people disagree here, I recommend to understand the question properly, it did not ask for a counterexample or whatever, but WHERE DOES THE PROOF BREAK DOWN. Actually none of the answers really answers the question, which is also obvious.)
So how can this most obvious unequal treatment be explained? Is it because the guy that deleted my answer is a friend of the other one or is it because he believes in "reputation" (which is a misnomer at any rate)? I should say that this is not so much about this particular question, but a matter of principle. It is clear that there are many other cases.
