Wrong.
They have a word for it. It's "ignorance." Secret has its own meaning.
"Secret, n. something that is kept or meant to be kept unknown or unseen by others." A secret requires the information to actively protected by some measure.
"Ignorance, n. lack of knowledge or information." That speaks for itself.
Learning the difference will serve you well in life.
Wrong again. My not knowing or caring who you are doesn't make it a secret. It makes you anonymous, at best. (Which has its own definition, just as an side. Feel free to look it up if you don't believe me.)And no, me not actively sharing who I am in real life is what makes it secret. You have it ass backwards.
Wrong yet again. I even gave you an example (well, technically, you gave the example and I just pointed out how wrong you were still yet again) with the Death Star's plans.Again, the standard you apply for secret makes literally nothing a secret. So when you claim something is a secret it is solely because you say it is.
