The question is not whether facts exist, but whether you actually have all of the facts and thus are accurately applying those labels. In my experience, people rarely do apply them accurately, hence, this reduces to you just disagreeing with these people's opinions.

Which is all besides the point. If you think they are grifters and conspiracy theorists, you are free to simply not listen to the podcast. The real question here is whether anyone else should be able to listen to it, or whether it should be censored due to actual harm. I asked if you have actual evidence of such harm, and this is the only question that needs an answer.
