What absolute drivel. It sounds to me like you have never listened to a piece by Wagner, nor even browsed a libretto.
Like all great artists through the ages, Wagner’s music came about through a love of music and a drive to create. Far from being intended to justify hate and discrimination, it is instead an expression of the romantic nationalism found all over the continent at this time and a love of the romantic and heroic sagas and myths which were likewise hugely popular all over Europe.
Was he an anti-semite? Sure he was. Just like at least half the population of any Western nation was at the time, to some degree or other. Blame the Holy See for that.
To compare Wagner’s musical genius to a semi-coherent pile of rancid dung like Mein Kampf is frankly cretinous beyond belief.
