Are People Really This Stupid?

So last night I went and found a new microwave. It's home, and it's set up and working. This morning I decided that I was going to go manual searching to see if I could actually locate an accessible version. I found it, and I started reading. Really close to the top was this warning: "Do Not Attempt to operate this oven with the door open." First of all, microwaves don't even turn on anymore if the door is open. Second, do these manual writers seriously think we're that dumb? HELLO!!!! SMILE! Stupid statement of the day!!!
