There is no free speech in the UAE.
There are plenty of Arab refugees in the UAE.
I was living and working in the UAE at the time when the UAE was welcoming Syrian refugees, they gathered up as many doctors, dentists, engineers, teachers as they could encourage to seek asylum in the UAE.
While at the same time the rightwing in the UK and Europe were rabble rousing against Syrian refugees.
Smart move by UAE, dumb move by the British/European rightwing.
