Trevor Noah hasn’t even begun his tenure as Jon Stewart’s replacement on Comedy Central’s “The Daily Show,” and critics are already clamoring for him to get the axe.

The reason? Twitter comments the South African comedian made more than a year ago that some have considered sexist and anti-Semitic.

After Noah was named as Stewart’s successor on Monday (Mar. 30), he was viewed as a daring, bold choice by the network— before the tweets came to light, that is.

Noah’s defenders believe that the criticism of his tweets are “unfair,” but according to Vox, "a Daily Show host should be held to a higher standard than other comedians."

"These jokes are offensive because they are reflections of cultures that are oppressive and privileged,” wrote Kelsey McKinney. “And rather than being critical of those societal constructions, the jokes instead reinforce them."

Noah took to Twitter today to defend himself, citing that he’s evolved as a comedian during his time as an on-air contributor for the show.

As with any controversy in the Twitterverse, there were those like Daniel Tosh who took an opportunity to make light of the situation.

Jokes notwithstanding, it was Bloomberg Politics' Dave Weigel who summed it up best, when he wrote that Noah went from “progressive icon to villain in 24 hours.”

What do you think? Do these tweets cross the line?
