Coloring books develop a lot of skills, and coloring according to contour develops discipline and accuracy, because creating chaos out of a coloring book doesn't really "break your bond" or anything.

Well, this is a bit tougher. Was it truly grammatically-incorrect, or did you just substitute a word for its synonym that makes perfect sense? In any case, this doesn't portray the system in any way, it just shows that you've been unlucky enough to get a very shitty teacher and that happens everywhere.

Dress-code at schools is fine, and banning super-short skirts/shorts on girls is understandable, since during puberty, guys can barely control themselves not to look at that extra inch of skin vs. studying maths. Dress code in my opinion is a lot better than people walking around in rainbow shirts and with green mohawks; schools are places of study, not party.

Once again, making "exit" sign on the door, especially in schools are made for organizational and discipline purposes. Here's an example: a bus has 2 doors on the same side, at the front and back. Driver asks people to enter from the front and exit at the back. If instructions are followed, people are moving in an orderly fashion, where nobody stumbles upon anyone. If people suddenly start chaos and start entering and exiting from both doors, it will most definitely cause delays, people won't be able to move as quickly in or out of the bus etc. You're being waaaay too skeptical about things. Our society worked by the word of law since the Roman era, and worked just fine. What you're saying is a perfect example of anarchism: a door says "no entry: personnel only" and instead you bash the door in. The surgery room says "wash hands, put mask on" and instead you operate with dirty hands with your hairs falling into the guts of the person.

I'd worry more about our society in terms of moral losses.

But like I said, if you have an idea about an alternate system, feel free to share.
