I hope you're not in any role where you can decide these things, because I think your opinions around this seem very harmful to both individuals and society.

Ignoring what we're fighting about, just think of what you said there. You are saying (correct me if I'm wrong) that we should just not allow people with opinions that contradict you to not have any power

Sorry if I came off rude or I'm putting words in your mouth but stuff like that is not ideas I take lightly. I think it's a threat to democracy

EDIT: I also hate stuff like this that directly attacks the person with the ideas. I have noticed that the replies to you became a lot ruder after you said that (probably it rubbed off.) I thing it is important to be calm in a discussion

Back to the topic

You're comparing a TED Talk that you chose to watch to school curriculum.

Teachers regularly put informational videos (including TED talks) on in the classroom. It never becomes less interesting because it's forced upon me - if anything their a nice change of pace

Those mistakes are from being not restrictive enough

Can you please elaborate. What "mistakes" did you make and what do you do now (also please elaborate on the "mistakes" society made)

Also please elaborate on the "effect"
