Although I didn't read all of it, this article appears to me to be an excellent antidote to Empire propaganda that is spread by media corporations.
In the current environment, to express even a mildly dissenting opinion, point out basic but unwelcome facts such as the presence of significant public support for the government in Syria, or highlight the frequently brutal acts of rebel groups, has seen many people ridiculed and attacked on social media. These attacks are rarely, if ever, reasoned critiques of opposing views; instead they frequently descend into personal, often hysterical, insults and baseless, vitriolic allegations. Generally, a set of core arguments are used to denounce those who question the dominant narrative.... The policing of acceptable opinion in this way has a simple and practical function: to foster a climate in which people feel too intimidated to speak out, thus allowing the dominant narrative to remain unquestioned so that, crucially, it can continue to be utilised to generate public support for further Western intervention in Syria. ....
...this is a strategy with a well-established precedent; the treatment given to many opponents of NATO’s assault on Libya in 2011 and the US/UK invasion of Iraq in 2003 are obvious recent examples. Unfortunately, it remains an effective means to stifle dissent and establish the acceptable parameters of mainstream debate. Its success has meant that those in favour of greater Western intervention in Syria have virtually monopolised the popular debate and control the narrative.
I have not been silent on the issue in the public domain, but frankly I too have occasionally found myself feeling intimidated.
