you clearly see the swords emerging from a backpack, and the dress she wears proves that it is not conected to her back. And to forestall the next comment we saw the swords folded up in such a way that they could fit in that pack very easily, and they unfolded in midair after being released.

the jet incident isn't because of her normal weight. Weiss could knock Penny over easily enough. Either the swords did something or Penny did, in order to enable that trick. We see the swords floating so they could have pulled, or Penny could have a gravity related semblance or something similar, which is why they were floating to begin with. Either way, that isn't anything you can't have a human doing.

obsession with friendship is the worst argument yet. you are far more likely to have a lonely person obsessed with friendship than a machine, so that actually hurts the case.

In short, people have taken details about penny that are at best shakey and at worst completely misinterpreted, and imediately drawn a conclusion that in reality has little to back it up.
