I grew up in the Midwest as a child of a Mexican and American. By 16, I was regurgitating Ben Shapiro anti-immigration rhetoric. Why?
The same reason anyone is racist. I grew up around it. The people I knew and loved were white and that was reflected in the media I was exposed to. Subliminal messages and implied suggestions over entire childhood. They might claim they don't like the illegal, but the truth is that they've internalized the hatred of the culture they identify with.
I don't know what's worse. Deporting children to a country they've never seen or deporting people who've been here longer than some of us have been alive.
You can come on a visa, seek asylum, overstay. It's not improper entry or illegal presence, it's exempt for asylum seekers.
ICE is arresting people who are coming legally. People who never chose to come here. People who've done everything right.
