No one is claiming that 'people are illegal'. That makes no sense anyway.
A person's legal status can be illegal, specific to their not being authorized to be in the country.
'Illegal Alien' and 'Illegal Immigrant' are commonly used descriptive terms for individuals without legal authorization to enter or remain in country.
It is not whether a person is illegal.
The 'solution' is to not permit people who are unauthorized to be in the country into the country, and to remove those who are not authorized.
So much projection and unfounded assertions and assumptions here.
The 'white replacement theory' is a theory of the democrats.
Biden and Myorkas have been planning to implement their 'Replacement Theory' for years, and this is it.
Which many of the Democrat leadership support, given their constant talking about it.
Yes, it's THEIR 'Replacement Theory'.
