How do you moderate something you can't define?

Hate speech can be defined. Of course, not everyone will agree on the definition, but that's beside the point.

I mean, isn't that exactly the point the person above is making?

I'm not sure, but either way my question remains. What if moderation of hate speech is part of the product?

Well that's why we need more choices.

...so that they have to compete to levy the most reasonable, well articulated, and transparent policies.

There are other choices, consumers just don't want them.

> I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description ["hard-core pornography"], and perhaps I could never succeed in intelligibly doing so. But I know it when I see it, and the motion picture involved in this case is not that.

Hasn't stopped the government from moderating other things that can't be defined crisply.

That's also a problem.
