Yes, those both make sensible tests of a nation's freedom. The freedom to make idiotic, racist remarks and the freedom to have easy access to the means to kill fellow citizens. Britan scores badly on both of those. But I would also propose another test - are you allowed to see images of naked men and women - and their genitals - on terrestrial TV channels?
Here I think Britain has the edge.
Yes, we have the freedom to make idiodic and racist remarks, but we also have the freedom to denounce those who make them. The important thing to remember, though, is that we have the freedom to tell the truth, even when the government, or anyone else for that matter, doesn't like it.
We also have the freedom to have the means to take the life of an innocent person, but we don't have the freedom to take that life. We do have the freedom to use weapons to defend ourselves against those not so innocent people who would take our lives. Most importantly, however, we have the right to arm ourselves to defend this nation against those who would try to deny us our God given rights.
I'm O.K. with Britain having the edge over us on the ability to see the genitals of other people on your "terrestrial TV channels". I value my freedom to tell the truth and to worship God more than my freedom to see naked people that I don't know. If that was important to me, however, I have satellite TV, so I can see all of the genitals I want. I haven't watched the "terrestrial TV" stations in years.
