Just because you perceive someone’s actions a certain way doesn’t mean that matches their intent. Perhaps you can politely take your preconceived notions and negativity out of the conversation and get back on topic. Also, apologizing before making an unfair comment doesn’t make it ok. But now really back on topic…
People usually like to listen to music while they’re working, but research looks mixed on whether it helps or distracts, and it likely depends on the type of music/sounds. Pretty much every time I’m at the space (which isn’t even all that often), someone in the workshop is playing music or videos on their phone, laptop, radio, something, at a level others can hear. Why are speakers a bad alternative to this practice? No one is encouraging blasting music at full volume. And I would rather not have my laptop or phone laying out in the workshop for fear of them getting broken by myself or another member. I think headphones would usually be preferable, but sometimes cords hang in the way or aren’t ideal when you’re working with others on a project. Speakers at a low volume sounds like a good option depending on the scenario!
