I can point to legal experts who have a different conclusion.[1] Your linked experts are not inherently more right than mine.
Would you acknowledge that there is something more incendiary about a member of the German Parliament denying the Holocaust in an official Parliamentary speech compared to a foreign national denying the Armenian genocide in Switzerland where the Armenian population is estimated to be 3k-6k? That is the primary conclusion of the ECHR. There is no justification for extrapolating that out to the idea that every instance of denying the Holocaust is worse than any instance of denying the Armenian Genocide which appears to be your conclusion.
