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.

You think that now it is better ?
People of Iraq were suffering exactly how under Saddam?
Now many of them are dead because of the war. Infrastructure destroyed. Many people are suffering from ecological disaster (depleted uranium and toxic waste where us bases were located).
And still there's no peace and no democracy. To everyone in the world outside the US is obvious that war was for the oil, not some mythical "democracy". And the life of people of Iraq had become much worse as the result.
