In a brewing scandal that should shock and trouble all of us, Exxon silenced us this week.

We put together a nationally crowdfunded PSA, promoted by thousands online who threw in a dollar or a click or both in favor of two simple ideas: we should be able to get the word out about the most pressing issue of our time, climate change, on television primetime; and we should be able to demand that our tax dollars stop being used to fund oil, gas, and coal.

We had already aired the ad, called Exxon Hates Your Children, to great acclaim in Denver, New York and Washington DC. But when we bought time in Exxon’s backyard, Houston, on the most pro-Oil network on televison, Fox News, something snapped – and Exxon decided to issue a cease and desist demand and threaten Comcast into not airing your PSA as scheduled.

That’s right: the richest company in the world couldn’t stand even 30 seconds of criticism on the airwaves. And they went after you, and your right to have a voice in national media.

Enough. We might not agree on everything, but we can all agree on this: When the richest company in the world takes aim at silencing even a moment of dissent on the airwaves, it’s taking aim at all of us. And we won’t let them do that. The issues we face as a nation, as human beings, are too important. The values we treasure are too big. And our voice is too needed.

Join us in telling Exxon: No. Just no. You don’t get to take our voice away. You can’t silence us.

P.S. You can watch the PSA Exxon didn’t want you to see here:
