Apart from public displays of affection how is that much different to Singapore? Singapore oppressive heat and humidity. Tick. Homosexuality illegal. Tick. Common over the counter drugs banned. Tick. (actually you need to check EVERY country you travel to as many countries are not as liberal as Australia in this regards, but guess you only heard that about the UAE because people on here in particular are looking for downsides to nit pick Qantas' decision to transit UAE) Severe punishment for something as simple as chewing gum. Tick. Boring. Tick.
Bottom line is every country has pluses and minuses. You don't like the UEA, fine, many don't like Singapore either, me being one, I reckon it is boring as bat poop after the first few visits. For staff working for Qantas they are paid to be there, it is not a holiday. In my work I am in the same situation, I get to go to places I wouldn't choose to go to as a holiday, but I go because it is my job. Oddly though most places I have had a negative view of before going it generally changes after I have actually visited.
