For some reason, people in crowds think that performing on stage also means giving consent to whatever happens, and that’s just fucking ridiculous. It’s not okay to run up to someone on the street trying to kiss them. When that happens, it’s called assault. So why do people think it’s okay to do it to performers on stage? Forcing yourself onto someone is never okay, regardless of the situation. Just like wearing a short skirt or being a sex worker doesn’t mean that you are giving permission for random people to grope you. The same goes for people on stage. Just don’t fucking do it. Do not objectify people based on their career choice or wardrobe or whatever lame excuse you’ve cooked up in your head that you think excuses you from the liability of real life assault. It’s common sense, really.
Everyone, and I mean everyone, has boundaries and feelings about personal space. This doesn’t all of a sudden disappear when someone straps on a guitar, stands in front of a keyboard, or takes hold of a microphone. Part of performance is being an extrovert, but it’s important to remember that it always remains a performance.
