So since Arabian horses are the most well-known/majestic/expensive/iconic/revered horses in the world then you think about Arabs each time the word horse is mentioned? Some people do which is idiotic to put it mildly.
Camels are not native to the Arab world but the Horn of Africa. More wild camels live in the Horn of Africa and Australia than anywhere else.
Besides what have animals to do with racism or a race? Do you think about Black people and Sub-Saharan Africans when lions are mentioned, LOL? The Arab world has a very diverse animal life so plenty of associations to pick from. To attach animals with ethnic groups or people is extremely silly when those animals, in this case camels, are not even native and found across the world.
Some people associate Turkic people with camels too, especially the more Turkic people in Central Asia. Besides historically camels played major roles in the most ancient civilization on earth (those in the ME) and outside of it and where the most expensive way of transportation on land outside of horses. They are clever and useful animals although I am not familiar with them as animals but that's what most people say and history shows.
Not that I know about. I have not seen those types of camels in the Arab world either. But I once ate camel meat in Egypt and it was quite tasty. Do you eat them in Turkey or what?
