The only irrational behavior going on here is unfollowing someone simply because you disagree with an article they've written. For a civilized, free society to thrive, we need to entertain opinions that we don't agree with and then have it out in the marketplace of ideas if we feel so moved.
I certainly don't agree with everything Jessica writes or has even written in this article; I may even disagree with more than I agree with. But she's not spewing talking points and she means what she says.
Stick around. You might learn from your disagreements.
