Former White House adviser Dr. Sebastian Gorka commented on the rise of Democratic socialism, saying that under it, equality doesn't exist.

Gorka said Saturday that New York gubernatorial candidate Cynthia Nixon "has no idea what she's talking about" if her remarks on the movement are true.

Nixon stated Friday that she’s proud to identify as a Democratic socialist, a "small but growing" group.

Speaking at a Netroots Nation conference in New Orleans, Nixon further pushed her stance on protecting immigrants from deportation and abolishing Immigration and Customs Enforcement.

Nixon joins another political newcomer in New York, congressional candidate Alexandria Ocasio-Cortez, as prominent figure identifying with the Democratic socialist movement.

Ocasio-Cortez surprisingly won her New York Democratic primary in June but has recently been called out for campaign missteps like getting her political colors mixed up and criticizing Israel’s "occupation” of the Palestinian territories during an interview.

Gorka said on "Fox & Friends" that the history of socialist movements has shown that only a small number of people have power while the rest of society suffers.

"It's very simple. This system crushes human souls," Gorka said, adding that under socialism, equality is a lie.

He said that radical Democrats like Rep. Maxine Waters (Calif.) have taken over the party as a whole.

"The lunatics have literally taken over the asylum when it comes to left-wing politics in America," he said.
