You are pointing out hypocrisy. The problem with that is that hypocrisy is a minor issue relative to the tyranny of removing the freedoms of Americans. If you remove the hypocrisy, say be vaccinating illegals, then the evil still stands. The right thing is to remove the Covid tyranny from everywhere, not by adding it to the border.
Illegals aren’t Americans. It’s not hypocrisy.
I have no problem treating them the same way our ancestors at Ellis Island were treated, which means screening, quarantining, treating or turning away those with serious illness.
