Rick Hummer, an emcee at a flat Earth conference in Denver, looked into a sea of people and asked them to repeat three words.

“I’m not ashamed,” Hummer said.

The crowd eagerly responded.

“I’m not ashamed of ridicule,” they chanted. “I’m not ashamed of mockery. I’m not ashamed of insults.”

Mocked and demeaned daily by family, friends and even strangers, hundreds of flat Earthers rejoiced with like-minded folks Thursday during the second annual Flat Earth International Conference at the Crown Plaza Airport Convention Center in Denver.

The two-day conference, put on by Canada-based Kryptoz Media, was packed with presentations and debates promoting and celebrating the theory that the Earth is flat. What exactly would a flat Earth look like? Well, that was up for debate, even among this crowd.

Scientists have long since determined that the Earth is a sphere. It is not up for debate in any scientific circles.

Despite overwhelming evidence, this group doesn’t buy it. The moon landing? Suspect. The Apollo mission? Problematic.

After Hummell led his call-and-response, he introduced Rob Skiba. A popular YouTube character in the flat Earth community, Skiba pulled up a PowerPoint called “Debunking Flat Earth 101.” Then he whipped out a white lab coat.

“I have no academic credentials,” he said. “But I do have a cloak of credibility.”

The crowd cheered.

Scientists, he continued, get away with misinformation because of their air of authority. Neil deGrasse Tyson, Bill Nye the Science Guy and Elon Musk were favorite targets of this crowd. As were NASA and the media.

Skiba started his presentation with a reminder that everyone in the room went to the same schools as the rest of the population. They read the same books, watched the same movies and visited the same museums.

“Never forget,” he said, addressing the globe-believers, “we used to be you.”

Charles Whitehead, who traveled from New Jersey, thought the theory was ridiculous when he heard it in 2016.

Then he listened to the rapper Bobby Ray Simmons — aka B.o.B. — talk about it. Whitehead watched some videos and realized he couldn’t prove the rapper wrong.

Since he came out as a flat Earther, his family relationships have taken a hit.

“My family ridicules me,” Whitehead said. “They say I’m stupid or I’m crazy.”

The flat Earth conference made him feel accepted.

“These people are like family,” he said, looking toward others wearing flat Earth hats and T-shirts. “I want to be around people like me.”

The conspiracy theories flowed freely, often far beyond the Earth’s limits.

James W. Lee sat at a booth, promoting his book, “Flat Earth: Investigations into a Massive 500-Year Heliocentric Lie.”

After speaking animatedly about various flat Earth theories, he launched into an explanation about powerful people using lasers to start the California wildfires as part of a plan to lessen the population.

Robbie Davidson, the man who put the conference together, strolled around the cavernous hall, conducting interviews with a stream of media outlets. He wanted to pinch himself.

“If my future self came to me and said we would have a conference with this many people,” he said. “I would have slapped myself.”
