These are pretty low-level bullshit questions, I think they are from physics.stackexchange, not theoretical physics. Can we can zero out their upvotes until they get real upvotes here?
Similar considerations for other low-level questions, I think we want to encourage real physics, not the usual philosophical blather.
The "What is logical positivism" business might be suitable for meta, so we can point people to it if there is no content to something.
