"Because they do" is really vague, but a more useful way of saying the same thing is "repulsion is an observed property of some physical objects due to the force of magnetism" is a better answer. Feynman was creative and coy with some of his answers. That doesn't mean we all have to be.

The "Human Rights" discussion is different from a law of physics. It is a human-curated list of rights and they all have restrictions and exclusions, which is core to the "censorship by private companies on their properties" discussion.

It's helpful to discussions of "Human Rights" or "Natural Rights" to point to a written document that disambigautes the terms and enumerates the specific rights, so we know we are discussing the same thing.

The UN Declaration of Human Rights Article 19 says

> Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers.[1]
