Some of those responses are ridiculous. "Actors need to be more appreciate of audiences"? So that means actors should just let someone seated in the front row continue doing something they've been explicitly told not to do, which is also illegal?
To me, there's no difference between a teacher who interrupts a lecture to admonish a student for texting & an actor stopping a performance. Broderick was within his rights.
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
