It's not “virtue signaling” to say that someone should not use their platform to foment deadly misinformation. Rogan isn't talking about sports, or debating whether someone's music is better than another artist's, he's giving weight to people who are pedaling advice which will reliably harm people.

It's especially interesting to see you attack the scientific consensus as a “biased narrative” because that's what you are actually trying to promote. The scientific process isn't perfect but it includes a lot of effort to avoid bias, starting with how things like experiments are designed and conducted. Claiming that someone else's politically-motivated position deserves equal weight is revealing that the problem here isn't bias but rather that it's not biased in the direction you would like.
