There was a time in America when the Left could be counted on to defend free speech. But as countless examples today demonstrate, those days are long gone. From campus speech codes to campaign finance to prosecutorial threats against climate change critics and more, the evidence is as fresh as this morning’s newspapers.

Campus assaults have been so well documented by the Foundation for Individual Rights in Education (FIRE) that they need no elaboration here. But the latest campaign finance “reform”—“until the court reverses its decision in Citizens United”—can be found championed in an op-ed in this morning’s Washington Post by such stalwarts of the Left as Yale Law School’s Bruce Ackerman and Ian Ayers. On Tuesday last, it seems, Seattle voters approved a measure that would “give” each registered voter a $100 “democracy voucher” that could be spent “for only one purpose—to support their favorite candidates for municipal office.” The city can of course “give” that $100 voucher only if it first “takes” the $100 from its taxpayers, which it will do in all the unequal ways that modern tax systems exhibit. Thus is the political speech of private individuals reduced by forcing the funds they might otherwise direct to candidates of their choice to be redirected through this public funding scheme to candidates they may oppose.

But that inroad on free speech pales in comparison to recent attacks on what most Americans would have thought were the free speech rights of climate skeptics, the RICO-ing of whom my colleague Walter Olson has been covering—along with the machinations of New York Attorney General Eric Schneiderman. The latest from the latter is all over the papers today, the Post’s headline reading “Exxon investigated over climate change research.” The Left has already browbeaten Exxon Mobil into ending its funding for think tanks and advocacy organizations that express climate change skepticism. Now, however, it’s getting more serious, with Schneiderman issuing a subpoena that focuses, we’re told, “on whether Exxon Mobil intentionally clouded public debate about science and hid from investors the risks that climate change could pose to its business.” “Clouded?” What, a debate that is crystal clear? That of course is what the environmental establishment would like as to believe.

And circling back to the academy, so too, apparently, would one Naomi Oreskes, a professor of the history of science at Harvard University and a critic of Exxon who laments that we haven’t yet implemented a carbon tax. There are many reasons we haven’t, she tells the Post, but a significant one “is the role of Exxon Mobil and others in fomenting disinformation, undermining public support for such initiatives, and lobbying against policies that would have begun to decrease our fossil fuel dependency.” And this from a professor of the history of science, the annals of which are littered with the corpses of “settled science.” Clearly, if we don’t stop this speaking and lobbying, we could have one more corpse.
