American democrats and human rights organisations do bring up persecution of minorities in India. Muslim countries don't care. They persecute their own people, why would they care about foreigners. They look to America for leadership. Few would have known about Rohingya if Time magazine hadn't put Buddhist fascism on its cover. So, the West has at times selectively stood for Muslim human rights; if they are not into terrorism and extremism, and not against western security. For example, Darfur, Myanmar, Xinjiang.
