By that logic, Neil Young is also dangerous. Technically they're both as dangerous as any other media personality or entertainer with a mic (or platform) and an opinion. You shouldn't be listening to Rogan without questioning, nor should you listen to MSM without questioning. Treating what they say as something that needs to be curtailed is at best patronizing to the millions of people that are in the audience, and autocratic/authoritarian at worst.
Saying that he's specifically dangerous (without highlighting that it's the same for others in MSM) is in fact dangerous because it's cherry picking what fits your biased narrative.
