Was there something comparable in Singapore or UAE? If so, I haven't heard about it.
But we hear about human rights abuses in Saudi Arabia and Israel/Palestine all the time, so I don't think your claim that "it's never a problem when human rights violations happen in a countries that are allies of USA" is valid.
I assure you it's not true. Democracy, human rights, freedom of speech are things that are very vaguely defined. It means that you can blame anyone arbitrarily for being insufficiently "democratic". This is what USA actually uses as a pretext to declare a war for resources. You can call any country "undemocratic" for some definition of "democracy".
"Democracy", "freedom of speech", and other abstract concepts, doesn't affect the daily lives of 99.9% of population. Most people do not care: they wake up, have a breakfast, go to work, come home, have a dinner, go to bed. They do not really care what is exact way the president is elected (or not elected). They do not care about so-called "freedom of speech" because they aren't journalists or writers.
On the other hand, when somebody drops bombs and rockets on you and your family, when infrastructure (schools, power lines, roads and other things) in your country are destroyed for tens of years, when there's anarchy and chaos around that causes huge rise of crimes, it makes a great difference to the everyday lives of the people. And that is what US/NATO really brought to people of Iraq, Libya and other countries.
