How is using the government to attack political enemies acceptable in USA?

So there has now been cases where ICE has specifically targeted political enemies without legal grounds in trying to revoke their citizenship and deport them.

For example, here is Mahmoud Khalil being apprehended without criminal charge by ICE, first to try revoke his student visa, which is bullshit because he did not have one and once they figured out he actually had a green card they switched to try revoking that instead so they could deport him. Such an obvious attack based purely on Khalil being a political enemy since they have scrambled to attempt to find legal grounds to justify what they have already done.

Another example is 10-year-old girl who has brain cancer and was deported with her family even though she is a US citizen through birthright.

At this point the mask is well and truly off. Any pretext that this is just about enforcing the law or protecting Americans is laughable. This is a political purge of the country using highly illegal means. I think its time to stop pretending that the Republicans are for law, rights or freedom. They obviously dont give a single crap about any of that since they are cheering on these tyrannical atrocities.
