To understand what the Trump administration is thinking about separating families and locking kids up at the border, you have to understand Stephen Millers foundational political belief: Its better to stir controversy, at any price, than it is to engage constructively.
The architect of Donald Trumps immigration policy and the White Houses resident troll, the 32-year-old White House senior policy adviser believes its good to trigger the libs, so to speak, with the purpose of enlightenment. To Miller, working constructively across the aisle isnt as useful as melting snowflakes.
To Miller, theres no reason to moderate a view or a policy, especially not when it comes to his deepest passion: immigration restrictionism. Its a subject he was passionate about even in high school and one over which he bonded with his former boss, then-Sen. Jeff Sessions, a longtime immigration hardliner. Its no wonder, then, that Miller designed the initial version of Trumps travel ban, barring people from several majority-Muslim countries from entering the US for 90 days, and refugees for 120 days.

Cruelty as a feature, not a bug
The Trump administration hasnt really tried to win the public conversation on family separations. As conservative writer Ross Douthat pointed out on Twitter, the policy didnt begin with a public discussion or explanation for separating young children from their parents, or by making the case to Congress for more family detention facilities. It started by taking kids from their parents first and attempting to assuage demands for legislation later.
