I’m not American, but the UK government does have the nasty habit of repeating the same mistakes as the US. Blocking sites on the internet is against freedom. It’s the sort of thing that “repressive” regimes do.
Remember the Arab spring, when it was “oppressive” to shut down the mobile phone networks, when protesters vented their rage in Egypt? Remember the British MPs who advocated the Blackberry messaging network should be shut down during the UK riots in August?Do they know what duplicity means?
Freedom of speech is a given requirement of democracy. Shutting down access to sites is just another form of Orwellian doublethink. If you can, do something. Go to http://americancensorship.org and tell them to stop.
