Why do Democrats oppose detention and repatriation of illegal aliens?

I'll keep it simple so over-educated Democrats can understand it. They want to to increase the number of illegals. Here's how.

To Boost population numbers in blue states to gain more seats in the House of Representatives.
To Secure more federal funding tied to inflated census data.
To Create a massive dependent class to justify bigger government and social programs.
To Grant eventual citizenship to illegal immigrants to form a new, loyal voting bloc.
To Replace the Black vote, which they’re steadily losing, with a new demographic they believe they can control.

Have I left anything out?
