I'm going to believe what they say:

https://www.dsausa.org/

"The Democratic Socialists of America is the largest socialist organization in the United States, with over 100,000 members and chapters in all 50 states. We believe that working people should run both the economy and society democratically to meet human needs, not to make profits for a few."

"Capitalism is a system designed by the owning class to exploit the rest of us for their own profit. We must replace it with democratic socialism, a system where ordinary people have a real voice in our workplaces, neighborhoods, and society."

"democratic socialism" is an oxymoron. socialism conflicts directly with democratic values. At the very least there is no pre-existing example of democracy and socialism working side by side. All previous socialist "experiments" were not democracies.

They themselves literally say out loud that they want to abolish our existing institutions. If you want to debate that point, go debate the DSA candidates themselves.
