This week it prevented users from hearing the views of Democratic presidential candidate Robert F. Kennedy Jr. Despite Kennedy running on the failures of the pandemic response, YouTube will not allow users to hear what it considers harmful thoughts.

On Sunday, both Kennedy and podcast host Jordan Peterson tweeted that they were the latest to be censored by the company. Kennedy tweeted: "What do you think… Should social media platforms censor presidential candidates? My conversation with [Peterson] was deleted by [YouTube]."

He added: "Luckily you can watch it here on [Twitter] (thank you [Elon Musk])."

The incident shows why many on the left continue an unrelenting attack on Musk and Twitter.

Musk eliminated most of the company's censorship system and, despite a few censorship controversies, the site is now the most open social media site among the major companies.

A Google spokesperson told Fox News Digital YouTube "removed a video from the Jordan Peterson channel for violating YouTube's general vaccine misinformation policy, which prohibits content that alleges that vaccines cause chronic side effects, outside of rare side effects that are recognized by health authorities."

Rather than allow experts and others to debate that question, Google and YouTube will not allow the debate to occur. It is consistent with calls from Democratic leaders for dissenting voices to be removed on subjects ranging from Covid to gender identity to climate control.
