Is this a Uyghurs attempt by ?

Yes.

Iran has been facing crippling sanctions from the USA that is equivalent to that of Cuba.

We should be especially careful with narratives from Western media (Human Rights Watch) and Western-allied media (Al-Jazeera).

I did a quick read of the HRW report, which cites numerous Iranian Human Rights NGOs based in the USA, with one of them, on their wikipedia page even saying it was funded by the US Department Of State.

So much benefit of doubt is given to these Western aligned NGOs but not a single shred is given to an imperialized nation that is perhaps the only Islamic country on Earth to successfully and completely defeat Imperialism from it’s borders (except perhaps Algeria)?

Looking at the actual HRW report:

Immediately revoke all policies and repeal laws that legalize violations of the rights of Baha’is, including but not limited to:

• Article 12 of the Iranian Constitution

Oh Article 12 which states:

The official religion of Iran is Islam and the Twelver Ja’fari school [in usual al-Din and fiqh], and this principle will remain eternally immutable. Other Islamic schools, including the Hanafi, Shafi’i, Maliki, Hanbali, and Zaydi, are to be accorded full respect, and their followers are free to act in accordance with their own jurisprudence in performing their religious rites. These schools enjoy official status in matters pertaining to religious education, affairs of personal status (marriage, divorce, inheritance, and wills) and related litigation in courts of law. In regions of the country where Muslims following any one of these schools [fiqh] constitute the majority, local regulations, within the bounds of the jurisdiction of local councils, are to be in accordance with the respective school [fiqh], without infringing upon the rights of the followers of other schools.

So they basically want to reverse the popular revolution of the masses that overwhelmingly supported the Islamic revolution of 1979? Perhaps now we know what the geopolitical aims that this false narrative of persecutions and oppression is hoping to entail?

By the way here’s Article 13 and 14 of the constitution:

Article 13: Zoroastrian, Jewish, and Christian Iranians are the only recognized religious minorities, who, within the limits of the law, are free to perform their religious rites and ceremonies, and to act according to their own canon in matters of personal affairs and religious education.

Article 14: In accordance with the sacred verse; (“God does not forbid you to deal kindly and justly with those who have not fought against you because of your religion and who have not expelled you from your homes” [60:8]), the government of the Islamic Republic of Iran and all Muslims are duty-bound to treat non-Muslims in conformity with ethical norms and the principles of Islamic justice and equity, and to respect their human rights. This principle applies to all who refrain from engaging in conspiracy or activity against Islam and the Islamic Republic of Iran.
