Recorded? You obviously don't know what OB's voice sounds like. Only thing anyone heard was "How does he get more rights than me?" touted by NOT OB. Super intimidating.The protest was denied. The threats were not denied. The decision read something to the effect that threats and insults were shouted into the void, and did not deter MT from giving his speech and he wasn't intimidated by the threats.
The threats and insults were recorded, therefore they are undeniable.
Hats off to MT for not being intimidated by disrespectful and rude behavior by grown children.
