In my eyes it is the opposite.
Klitschko is a heavy weight world champion, Rogan should be excited to have him.
If he ignores it, it will be a clear signal that he isn’t independent as he claims to be, but also gets paid to spread Russian propaganda.
I don’t see how one would reject such guest unless the goal is spreading disinformation.
It looks like they are using the same techniques they used for trump.
Social media is cancer.
