The East in the Middle East (and frankly also the ‘Middle’) has nothing to do with it being in Asia.
If it did, Japan would likely be the Middle East. Or maybe Thailand, depending.
Instead, Japanese and Chinese are typically referred to as ‘East Asians’.
Usually, if someone is going to say anything at all about West or Central Asians, they tend to be referring to the ‘stans and/or Mongolia. Since Russia’s a bit… special. And takes up most of the rest.
The more you know.
I don't think there is any need for sarcasm. It's common knowledge that there are 6-7 continents (depending on how you want to count the Americas).
And most people in the English speaking world would be very confused if you tried - just like you were, when you tried to say it was because the Middle East was in East Asia.
"you tried to say it was because the Middle East was in East Asia". I didn't. This is what I said (quoted): "Middle East is a region in Asia". And you said "The Middle East is in Western Asia" which supports my point.
Most people in the English speaking world get confused with basic math (as indicated by studies by the OECD and Santander among others) or world geography (especially concerning territories outside the western world, this seems to be anecdotally true in the US).
Do you imagine people calling the Earth flat because "everyone says it is"?
