Why do you have to be rude? They were simply claiming the classes were not effective at their apparent goal of making students more ethical. It doesn't mean they don't think doctors should be ethical.

I also had to take a required ethics class, and it was the worst taught class I ever took there. It wasn't effective at teaching me about ethics, it was just a pile of bad tests, and it certainly wasn't effective at convincing me and the other students to be more ethical in our respective careers.

The free website where many people put up easy to access high quality educational resources is a great way to learn stuff on a budget. Not all of youtube is great but being rude to people who watch youtube videos to make yourself feel bigger is shitty.
