No one has called you or anyone else an idiot. I'm not sure where you've been or which iPhones you've owned, but EVERY iPhone ever made or sold has had screens which could scratch. These forums have been witness to loads of threads from people just like you and others here complaining their new phone scratched for just about every model phone ever sold. The easiness with which they can scratch has definitely changed over the last couple models for sure. I'm not going to post the links for you to read as you can take your own time to read through this thread where many links have been posted explaining the new generation glass, how it is 4 times less likely to shatter in a fall and that means it is more easily scratched. You see, there is no company who has been able to create a glass formula which is harder to break AND harder to scratch. If someone could create that, they'd become richer beyond their dreams. What is most different however, is how few people now complain their phone shattered and they will now have to pay $hundreds of dollars replacing it. Those threads have virtually gone away as the glass on iPhone and most other major manufacturers phones have become harder to shatter, while still being able to be scratched.
If you've somehow managed to never scratch a naked iPhone screen, you are most unique. This is one reason Apple has sold and installed screen protectors in their stores for every model iPhone ever sold. This is why screen protectors are a $Multi-Billion sales item from more sellers than I could possibly count. Just to go to Amazon and search for screen protectors for any modern iPhone and literally hundreds if not thousands of options can be bought.
I'm sorry your phone is scratched, but anyone who doesn't put an inexpensive screen protector on a phone costing now $1,000 OR more because their phone didn't scratch in the past is akin to buying a luxury car and not buying insurance for it because you never had an accident.
