You can't re-write history. It is a fact that in 1952 an animal was named this. Nobody is celebrating this - it is clearly pointed out that this was a bad name.
Although I'm not personally a fan of naming zoo animals - the fact is that many of them generally are named, and their names are very important to many people, especially on this site.
The fact that names are sometimes inappropriate is also important to highlight. We can't just put our fingers in our ears and yell "la la la la" about stuff like this. It's important to highlight how critical it is to choose appropriate names - and how names can become inappropriate over time, due to the changing nature of our language.
I am very aware that the name in question linked to in the first post is particularly triggering to some people - which is why the moderation team are discussing the thread. I would also assure people that I do take this stuff very seriously - for those who aren't aware, both of my children are of African descent and so I am extremely aware of how they might be treated in the largely white society in which we live (although thankfully this part of Sydney is quite multicultural).
So while it's funny to laugh at stupid names like X-Box or Trunky McTrunkface (has anyone actually tried to name an elephant that yet?) - there is a more serious side to the discussion that I think might be worth having.
As already mentioned - the moderation team are discussing it.
