This alarmism about fake news sites may shape up to be a free speech battle on social media. There are all sorts of lists now, including ironically from mainstream media, telling us which sites are propaganda or fake. They aren’t wrong on a lot of them but of course they don’t mention their own problems with the truth.
The pro-Assad libertarians are particularly alarmed since it would take out most of their sites–like 21st Century Wire. Most of what they write is rubbish but under the US Bill of Rights, they have the right to promote their views, just as mainstream media does.
It does point out an educational weakness–which is apparently international–that readers to not interrogate their sources sufficiently. If nothing else, this may make us more discriminating readers. Nevertheless, FB & Google do not have the right to tell us what we can & cannot read.
