I asked a question looking for resources on a specific case of gendered language: using the generic masculine for female individuals in different sentence constructs. A moderator closed this question because he believes it will lead to discussion and opinion based answers. Since I did not solicit opinions, he used the "duplicate" close reason with a somewhat related question about the idiom "ich gehe zum Arzt".
Since this is clearly not a duplicate, I assume the reason he gave in comments, i.e. that it would generate a familiar discussion, is the actual close reason.
It is true that some comments and answer attempts have expressed opinions on gendered language in general and not on the question, but a good answer is clearly possible.
Should we have a policy to close any question about gendered language at all, because it attracts opinionated answers, even if the question is clearly answerable? If not, could we reopen my question?
