Not that it matters who it is, that they are killing their own is the frightening part.

It's confusing for people who aren't used to dealing with special government forces. There's the regular Iranian military. Then there's the Revolutionary Guard Corps (IRGC). They are the regime's enforcers and secret police. They're the fanatically loyal ones. Then there's the Basijj, who are kind of like the neighborhood enforcers. They're the ones who spy on their neighbors and report them to the IRGC.

Today, the force consists of young Iranians, a significant portion drawn from the traditionally Shia cleric religious and politically loyalist parts of Iran's society,[9] who volunteer, often in exchange for official benefits. With branches in "virtually every" city and town in Iran,[1][13] the Basij serve as an auxiliary force engaged in enforcing state control over society,[14] acting as a morality police at checkpoints and parks, and suppressing dissident gathering,[9] as well as serving as law enforcement auxiliary, providing social services, organizing public religious ceremonies.[15][16] The force was often present and reacting to the widespread 2009 Iranian election protests, 2017–18 Iranian protests, and the 2022-2023 Mahsa Amini protests.[17] The Basij are subordinate to and receive their orders from the IRGC and the Supreme Leader of Iran.[10][18] They are said to be "tightly affiliated" with the Islamic Republic's "hardline" political faction,[9] and "routinely" praised by the Supreme Leader,[19] but also called a "profound source of disquiet and rancor" among the general public in Iran.[20] Following Operation Midnight Hammer, Basij forces has significantly increased its urban patrols, especially at night to “ensure security".[21]

As part of the IRGC's sphere, the Basij are indirectly designated as a terrorist organization by the governments of the United States, Bahrain and Saudi Arabia.[22] The Basij has been frequently implicated in human rights violations, including torture, rape and sexual violence,[23] enforcing sharia law on citizens such as the mandatory wearing of the hijab.[24][25][26]

In theory, the Basij are banned from involvement in politics by the Iranian constitution, but its leadership is considered active, particularly during and after the 2005 election of President Mahmoud Ahmadinejad.[8] In past elections militia members have voted for both hardliners and reformists. President Ahmadinejad received significant support from militia members, many of whom have benefited from his policies during his presidency.[65] Supreme Leader Khamenei described Basij as "the greatest hope of the Iranian nation" and "an immaculate tree".[18]

But, we never experienced that what they go through and we now fear it will happen to us and ICE will go live use in a matter of time.

It's only genocide if it's directed at an ethnic group. This is just wholesale slaughter.
