Former Democratic Socialists of America (DSA) organizer Jake Altman argues that over the past 10-15 years, the organization has transformed from a relatively pragmatic working-class social-democratic group into a much more radical movement driven by younger activists and open to more extreme ideas.

He describes internal pressure against dissenters, increasing openness to communism, and a demographic shift toward younger and more affluent, less experienced, and more radical members during an interview with The Free Press.

"When I joined in 2013, it was much more social democratic. It was very old, very white. In 2015 in Boston, it was a few older men and I who were the core of the old DSA chapter," Altman explained. "It is night and day between DSA in even 2015 and now. It went from this, like you say, pretty moderate social-political group to a cultural juggernaut that it is today."

"By 2014, a group called the Left Caucus was formed that advanced a lot of extreme views."

"There were debates at the time about how much Leninism do we want to let into DSA. And these people, they eroded any resistance and any core of anti-communism that remained within DSA. Anti-communism became forbidden, right? This is a big evil thing, to be an anti-communist."

"And you can't hold this view without running all the old people who experienced the 20th century out of the organization. And I think that had to have been part of the calculus, that they didn't want any internal resistance," he said. "And so there were instances where people were - I think efforts were made to silence people who dissented."

"I can speak from personal experience that if you dissent, there will be efforts to silence you. They use mob tactics, basically," he said. "So if you speak out, they will coordinate and a bunch of people will jump on you and denounce you, smear you behind your back, do whatever it takes to try to discredit you if you speak out against them."

"There was a local union in Ann Arbor who said it's too far to vandalize and intimidate public officials, vandalize their homes and intimidate them. That is too far," Altman said

"Immediately they received a swarm of people online responding to that statement, essentially saying, 'You're supporting genocide. Shame on you.' Trying to turn their members against them and stir up animosity towards them with the effort of silencing them."

"DSA itself makes a distinction - an important distinction - between paper members, who are people who give the organization their credit card and never come to a meeting, and cadre, who are hardcore activist members who show up to all the meetings and do all the work," he said. "The cadre are incredibly radical. The paper members might be, you know, think AOC and Bernie Sanders are great and let's get Medicare for All."
