Assalamu allaicumu wa raahmatullah wa baarkatuhu
Dear brother, duty of all Muslims is to enjoy good and forbid any kind of evil.Every Muslim has duty toward Allah and toward all our Ummah to advice other Muslims, and other people in general, to give dawah about Islaam, correct other mistakes and fight toward any kind of evil. This is also part of Islam, and not un Islamic. We are not living in Afghanistan, but it does not mean that we should not condem Americans for killing our Muslim brothers and sisters and we for sure know what Americans are doing there. It does not mean that we are slanduring other Muslims if we are correcting thier mistakes for the sake of Allah.
Allahs Messanger saalhu alyaha wa salam said: Who ever of you see something wrong, he should change it with his hand, if he can not than with his words,and if he can not he should change it at least with his heart but that is the most week part of eman" ( Muslim)
Allah subhan wa teala sais: " You [true believers in Islamic Monotheism, and real followers of Prophet Muhammad and his Sunnah (legal ways, etc.)] are the best of peoples ever raised up for mankind; you enjoin Al-Ma'ruf (i.e. Islamic Monotheism and all that Islam has ordained) and forbid Al-Munkar (polytheism, disbelief and all that Islam has forbidden), and you believe in Allah." ( Surah Ali Imran, ayah 110)
We are not living in Qatar but there are Muslims who are living there and who can pass our message to Muslims who are living there. To point on someone mistake which is made with clear mind that knows it is wrong, it is not backbitting, but advicing and warning for the sake of Allah.
We have example in our Prophet Mohammed sallahu alayha wa salam, who was always advicing and warning early Muslims if they commit something wrong,and even his Sahabahs r.a.
And also to say that advicing and warning others for the sake of Allah, is also from learning about Islaam and improving ourselfes like Muslims, because it is also good deed in the sight of Allah.
And Allah subhan wa teala and His Messanger s.a.w.s knows the best.
May Allah guide us all.
