Again, babies don't come out with clothes on. The idea of expecting consent for sending grandparents pictures of what their newborn grandchild looked like when it was just a few seconds old is ridiculous.
And yes, psychology is a soft science. That doesn't mean that you personally can claim that people have been traumatized by this without showing any evidence of it just like you can't claim that people have been traumatized by a Luke Skywalker action figure without showing any evidence of it. You can infer whatever you like. Inferences aren't truth and they are based on personal biases.
Suggesting that because psychology is a soft science, you can make whatever claim about trauma you infer is ridiculous. Where did you get your psychology degree from, anyway?
