They’re non-immigrants, remember?
If non-immigrants are going to continue to flood America on temporary work visas, then suddenly call themselves “immigrants”, then the entire work visa program is a criminal fraud on the American people perpetrated by a criminal government.
Fraud is always a crime.
The “hatred” comes from being lied to and robbed by criminal gov’t and criminal invaders who are entering under fraudulent pretenses.
