How can you be a fan of Dolly Parton and homophobic? One of her best stories is when she entered a drag queen Dolly Parton look-a-like contest and lost. https://www.yahoo.com/entertainment/claim-dolly-parton-entered-look-130000474.html

Whilst these incidents are rare, we have a zero-tolerance policy to bullying, harassment, or any form of abusive behaviour towards our cast, crew, or staff. Anyone engaging in such conduct will be removed from the venue immediately.

Uh, so why did the cast have to walk out and end the show? Drag the bigot out to the street: problem solved. The show must go on.
