Stephen Pinker published an essay entitled "Science is not your enemy", addressed to researchers in the humanities. Suppose one wanted to make an analogous suggestion to researchers in the sciences? Here are some options:

But "humanities" has the form of a plural, whereas "is" is singular.
The humanities are not your enemy.
Gloria Origgi posted article with this title, but if there are multiple humanities, wouldn't there be multiple enemies, i.e. that they are not?
The humanities are not your enemies.

Art is not your enemy; history is not your enemy; literary studies is not ... oops, are not, um ....
