It's unclear to me why this answer was deleted.
As one of the moderators yesterday wrote in another meta post about an unrelated answer:
Answers get deleted for being wildly off-topic, total gibberish, or outright offensive.
None of those apply to my answer. So why was my answer deleted?
I certainly hope it was not deleted because it didn't confirm to the mainstream opinion on this site. If that be the case, it would be very bad, as per the same moderator:
What Answers do not get deleted for is being wrong, let alone potentially wrong. [..]
If no valid reason can be given, please undelete my answer.
[Full text of my original answer, for those who cannot see deleted answers:]
What is the fundamental difference between catching whales and hunting other animals?
There is no fundamental difference between whales, and e.g. dogs or cows. All are mammals; Some people eat some (or all) of those, while some other people consider it immoral to eat some (or all) of those.
Therefore, the main difference is culture. Many people are used to eat beef, while they are not used to eating whale meat.
Undelete flag was denied:
declined - Moderators will not override community consensus unless the answer was substantially edited or the delete-votes were very clearly abusive. This doesn't seem to be the case here.
Despite every answer, plus two moderators in comments, stating that the answer should not be deleted, they still do not undelete.
