Nothing and everything. Joe Rogan’s ‘I’ll talk with anybody’ reputation which made his show so appealing at the start landed a lot of right-wing extremists on that show. People began to criticize Joe Rogan for not having any standards and giving truely horrible people a platform. Typically the more left leaning a person was the more they criticized him and this has slowly pushed his opinions to the right over the last decade. Additionally a lot of Trump supporters began to see Joe Rogan’s show as a means to popularize and legitimize their beliefs. Since Joe Rogan is so impressionable, and Trump supporters found a home there he made the final leap into right-wing conspiracy theories after Trump was elected and has been getting even more out of touch with reality ever since.
