Leftist keep trying to "say it to make it true". The facts are still out there.
I'm going to regard you as though you're interested in the facts. I know you're not, but hey, someone reading this might be.

Violent Crime 2024
Violent Crime consists of murder, non-consensual sex offenses and aggravated assault. Victims are always individuals. One offense is counted for each victim.
From the 2024 Immigration Report, we can also see that unlawful immigrants are reported as having committed 11 of those 587 homicides.

That is, as I'm sure you can tell, a smaller number.
That is to say, to borrow your phrasing, they "commit less crime than 'Americans' - the data proves it."
So your argument, that undocumented immigrants, whether or not they've committed a crime, should all be deported anyway, on the grounds that they're more likely to commit crimes due to their foreign-ness, contradicts the available data.
i.e., your racist ass is full of shit.
