According to the video:
American model of free speech, which largely rejects hate speech laws, is essential because governments and institutions should not have the power to decide which ideas are acceptable. They argue that restricting speech does more than silence offensive opinions, it shapes what people are able to think, discourages open debate, and makes society less resilient by suppressing controversial or unpopular viewpoints. While acknowledging that hate speech laws are intended to protect vulnerable groups, the speaker contends that in practice such laws mainly protect the authority and narratives of those in power. They conclude that true intellectual freedom requires allowing even offensive or unpopular ideas to be expressed so they can be challenged rather than censored.
In a larger scale of rights overall, your rights to do something should end when it restricts other people’s rights. No one person should be above another. Not really how the world works, but it’s the idealistic goal.
