I assume the last sentence was tongue in cheek.
Estimates for total illegal immigrants in the US range from approx 10 million up to approx 30 million. 800,000 is just the number of children who were brought illegally by their parents, through no fault of their own doing.
I have sympathy for that, but it doesn't change the fact the whole situation is retarded and people shouldn't be defending that level of mass migration.
Mass migration is fine if it is legal and the country where folks are immigrating to is allowing all the immigrants in with legal process.
That is not how the US ended up with 10 to 30 million illegals. They are called "illegal immigrants" because they came illegally
