If I'm not directly impacted by someones' use of PPE, then that's their business even if I think it is an overreaction or performative. I've injured myself while doing "simple" operations before when a bolt or screw unexpectedly failed, so it may not be as performative as it appears.

On the other hand, if I'm working with someone in a professional capacity and they are delaying our work because they are acting in an anxious manner about safety, then I'll take time to talk through why I see their actions as counter-productive and then we can discuss how to be safe and efficient.
