Stephen Miller is quite the attraction for Donald J. Trump and his administration.

The young policy adviser seems to relish appearing on TV simply to make inflammatory statements. Now we find out through some leaked e-mails that Miller harbored some dark and sinister thoughts about white nationalism and assorted racist philosophies.

The American Civil Liberties Union, the Black Congressional Caucus and the Southern Poverty Law Center and other groups all have called for Miller to resign. The White House stands by their man, presumably with the president’s blessing.

Of course he should quit. Miller had no business being involved in such a senior policy adviser role in the first place. He is a flame-thrower, a provocateur, a living, breathing symbol of the politics of division that have highlighted (or lowlighted) the Trump administration.

I say all that, naturally, knowing that nothing will happen as long as Donald Trump is president of the United States.

One batch of e-mails suggests that Miller favored restricting legal immigration from Third World countries, favoring a policy more disposed to welcoming immigrants from, um, blonde-blue-eyed regions of the world.

I believe Stephen Miller is a toxic dude. He doesn’t belong in the White House, let alone working hand-in-glove with the president of the United States.

Will he be shown the door? Hah!
