The Open Borders Left, or: I Hate Being Right All The Time

So here's a thing from the Women's March "Unity Principles":

IMMIGRANT RIGHTS

Rooted in the promise of America’s call for huddled masses yearning to breathe free, we believe in immigrant and refugee rights regardless of status or country of origin. We believe migration is a human right and that no human being is illegal.

Anyway: I've thought for a long time that it is more and more common for the American left to tacitly endorse open borders. And I don't see any way to read that last sentence that doesn't seem to offer confirmation of my view.
