Here I ask "Is there a poll on How people in US and UK think about selling weapons to Saudi-Arabia?" Thomas Hollis answers " As far as I can tell there is no poll..." . I am not sure if the answer is true, but assume that it is true. Then:
I wonder if it is appropriate to accept it. In fact if I accept it, it has two disadvantages; regarding the fact that "someday maybe a poll happen":
the question will excluded from those questions that don't have an accepted answer (result: less attention).
if a poll happen and one post another answer, then i should take the acceptation back (?).
