That does not follow. As Giles suggests, the UK does not have a law against Holocaust denial, and the UK is the relevant country for libel tourism, which is the only phenomenon you linked to.

Furthermore, the UK standards for libel are very old, and there has been some success in the UK in reducing them. This is partially in response to pressure from the US, which no longer extradites for speech violations that are not illegal in the US, in direct response to libel tourism.

I'd link to a reference with details on all this, but you already did.

I thought that libel tourism was basically a UK thing, which doesn't have a law against Holocaust denial.

I guess I'm saying:

• Different nations can have different Schelling fences
• Some nations can establish Schelling fences and others can be on slippery slopes. The strategy of the nations with Schelling fences would depend on the extent to which they care about the other nations.

And let's not forget the speech being banned under American influence.
