Re: I see what you are doing there...
"All websites/blogs/social media accounts with views/comments that specifically challenge or go against what the government is saying are creating a sense of fear within said officials, therefore one might say they are "terrorist content".
Not far from the truth, I fear. The current definition of terrorism, as found below, certainly would allow the prohibition of almost anything that the government doesn't like. Pay careful attention to the words used, especially the word "influencing". Just about anything can be called an "influence" and "force" can mean public pressure, popularism, or any kind of movement of persons or ideas - not just limited to actual, physical force. They may say that they MEANT only physical force, but this is a legal document and language in law should be/is an exacting thing. Be wary of such weasel-words.
"acts of terrorism" means acts of persons acting on behalf of, or in connection with, any organisation which carries out activities directed towards the overthrowing or influencing, by force or violence, of Her Majesty's government in the United Kingdom or any other government de jure or de facto.
