There is technically self-defense law in Denmark, as long as you don’t use something effective, like pepper spray. I can’t imagine any rationale by which a free society can tell someone they can’t carry and use even a defensive spray. Especially with this rape culture spreading throughout Europe. Denmark isn’t the only country. Even our neighbor to the north, Canada, bans defensive spray. Bastions of freedom, the countries of Saudi Arabia and Russia allow it. You can see the whole list of ridiculousness here.
The right to defend life and limb, and to have access to effective tools for doing so is not an American right, it is a human right. I would argue it is perhaps the most basic human right there is. It is a shame there are so many countries in the world that don’t recognize and protect it.
