Send Harvard's Chinese Students Home

I'm not familiar with WSJ and, due to paywall, I just read a few paragraphs... Still I wonder: is this satire or a genuine opinion? Because if it's the latter it's quite cringe.

EDIT: "Mr. Gallagher, a Journal contributor, is head of defense for Palantir Technologies and a distinguished fellow at the Hudson Institute. He represented Wisconsin’s Eighth Congressional District (2017-24) and was chairman of the Select Committee on the Chinese Communist Party".

Jeez...
