Democratic National Committee (DNC) Chairman Tom Perez Thomas Edward PerezClinton’s top five vice presidential picks Government social programs: Triumph of hope over evidence Labor’s 'wasteful spending and mismanagement” at Workers’ Comp MORE on Saturday called for party unity, rather than uniformity when it comes to political differences.

“We should never confuse unity with unanimity. Unity doesn’t mean you have to be a rubber stamp,” he told a crowd of party members during the DNC's first meeting in Las Vegas, Nev., according to reports.

Perez told the crowd that the DNC is stronger when unified, calling organization over targeting demographics the key to success in winning future elections.

"We will not win the future by re-litigating the past. Our unity is our greatest strength," he told the crowd before a contentious vote on new party members, BuzzFeed News's Ruby Cramer reported.

"I hear 'demographics is destiny' and it's nails on a chalkboard to me. Demographics is not destiny. Organizing is destiny," Perez continued.

His remarks come after receiving backlash from frustrated DNC members who stewed over the party's new slate of at-large delegates last week.

Some of the progressive-leaning Democrats felt they were demoted as retribution for their opposition to Perez during the race for his top party role.

Perez's remarks looked to dismiss these assertions, saying the DNC is "stronger because of all the people on this dais," adding that "that doesn't mean we don't have pitched discussions."

"We are a family," he added.

The chairman told the crowd his former boss told him he should identify with "the accomplishments wing of the party because you get shit done," Bloomberg's Jennifer Epstein reported.
