My question on the origins of the term "Holocaust" was migrated to another board. That's fine, but why does migration have to close out a question from the Judaism board? It would seem to be appropriate in both places.
As the FAQ list explains, q.v., questions about Jewish history are off-topic on Mi Yodeya. In fact, a specific question listed as an example of an off-topic Jewish-history question is "In which way antisemitic attitudes against Jews began to become more extreme under the Nazi regime?".
Migration is simply closure as off-topic, with the added benefit of simultaneously asking the question elsewhere (instead of only closing it as off-topic).
