New media writer Clay Shirky took to Twitter Friday afternoon to dismiss white liberals’ response to Donald Trump as ineffective and self-indulgent – and to rally them to defeat Trump.

“Believe this: Trump could win,” Shirky tweeted. “We can help stop him, but that means giving up on a lot of comfortable illusions.”

I want to say something to my liberal white friends: Trump talked a lot of shit last night, but not one word of “I am your voice!” was a lie — Clay (((Shirky))) (@cshirky) July 22, 2016

Trump IS the voice of angry whites. He wasn’t on stage because he has unusual views. He was on stage because he has the usual ones, loudly. — Clay (((Shirky))) (@cshirky) July 22, 2016

He is the voice of whites who want their neighbors deported if they speak Spanish. He is the voice of whites terrorized by seeing a hijab. — Clay (((Shirky))) (@cshirky) July 22, 2016

He is the voice of people who think legal & cultural privileges for white conservative Protestants are God’s plan, not a bias to be overcome — Clay (((Shirky))) (@cshirky) July 22, 2016

He is the voice of people who hear ‘hard-working’ as a synonym for ‘white.’ He is the voice of people who think black lives matter less. — Clay (((Shirky))) (@cshirky) July 22, 2016

He speaks for millions. — Clay (((Shirky))) (@cshirky) July 22, 2016

During the speech, a lot of white liberals in my timeline – people like me – were reacting in disbelief. We can’t afford disbelief, not now. — Clay (((Shirky))) (@cshirky) July 22, 2016

So, believe this: Trump could win. We can help stop him, but that means giving up on a lot of comfortable illusions. — Clay (((Shirky))) (@cshirky) July 22, 2016

The hardest illusion to give up is the majority illusion, where we confuse our neighborhood with the world. https://t.co/2Fm1pmB4Uf — Clay (((Shirky))) (@cshirky) July 22, 2016

Elections are a harsh corrective to thinking everyone agrees with you. Winning isn’t about policy, or passion. It’s about headcount. — Clay (((Shirky))) (@cshirky) July 22, 2016

Liberals cluster, in cities and in states. My home state, Missouri, has gone from purple to red because enough liberals left. — Clay (((Shirky))) (@cshirky) July 22, 2016

Meanwhile, California’s high-margin vote for Clinton will be wasted, because the election hinges on Ohio and Pennsylvania and Virginia. — Clay (((Shirky))) (@cshirky) July 22, 2016

I’m a white guy, so I’m an imperfect vehicle for this message. Follow @docrocktex26 and @jbouie, who serve hot coffee on this stuff all day — Clay (((Shirky))) (@cshirky) July 22, 2016

But I can remind other white people, as an insider, that the amount of white rage available for political use in America remains enormous. — Clay (((Shirky))) (@cshirky) July 22, 2016

“When you’re accustomed to privilege, equality feels like oppression.” — Clay (((Shirky))) (@cshirky) July 22, 2016

White liberals should know headcount is against us. In our communities, we’re a comfortable majority. In the US, we’re a permanent minority. — Clay (((Shirky))) (@cshirky) July 22, 2016

Most whites vote /against/ Democratic presidential candidates, and have done in every election since LBJ signed the Civil Rights Act in 1964 — Clay (((Shirky))) (@cshirky) July 22, 2016

When Democrats committed to reducing whites’ ability to lord it over blacks, it cost the party the white vote for two generations. So far. — Clay (((Shirky))) (@cshirky) July 22, 2016

The liberal cause has been saved by African-Americans, who are populous and disciplined and consistent enough voters to overcome white rage. — Clay (((Shirky))) (@cshirky) July 22, 2016

Unlike President Obama’s campaigns, though, whites can’t coast on minority Get Out The Vote work in 2016, not with VoterID laws in 33 states — Clay (((Shirky))) (@cshirky) July 22, 2016

Trump can win, if he can whip up white rage unchallenged, if enough women vote for him, and if Red states suppress black and Hispanic votes. — Clay (((Shirky))) (@cshirky) July 22, 2016

Trump can win, if he concentrates on white fear. Thats how you get white evangelicals to pick a libertine agnostic over a liberal Christian. — Clay (((Shirky))) (@cshirky) July 22, 2016

So what’s a white liberal to do? First, realize we are a minority, and we have to campaign like one. Donate to the campaign, for starters. — Clay (((Shirky))) (@cshirky) July 22, 2016

Yes, yes, Clinton’s not as liberal as we’d like, but minorities never get the luxury of demanding a perfect candidate. Just give. — Clay (((Shirky))) (@cshirky) July 22, 2016

Talk with pro-Trump relatives, because they won’t listen to people who aren’t white. (Statistically, they won’t know any they care about.) — Clay (((Shirky))) (@cshirky) July 22, 2016

Donate to fight voter suppression. https://t.co/CF8a45ThAY — Clay (((Shirky))) (@cshirky) July 22, 2016

In November, call voters, or better, get to a swing state and knock on doors. Get to poorer communities and drive people to the polls. — Clay (((Shirky))) (@cshirky) July 22, 2016

Trump has promised 40% of the country what they’ve always wanted: a racist welfare state. If he persuades 1 additional voter in 10, he wins. — Clay (((Shirky))) (@cshirky) July 22, 2016
