Given that this is the premise of your whole argument and is demonstrably untrue then I don't know what the point in responding to the rest is.
It is not the premise of everything, and cutting the argument short with another cheap trick is dishonest.
Are you really suggesting the US, UK, Europe et. al. have a secret great firewall like China, and have the same lack of plurality of media?
I suggested nothing of the kind. Western propaganda is fundamentally different and much less obvious than Chinese or Russian propaganda. For example, almost every Hollywood action movie portraits the US military in generally good terms (even if there are individual villains), and quite often they are the ones who save the world. The Pentagon, meanwhile, supports such movies generously with vehicles, equipment and other support. Coincidence?
There are literally books about how the western propaganda system works, who is connected to whom how, who owns the media and why, for examples, there are wars and genocides that you don't find on the evening news even though the body count far exceeds other wars that do get reported.
Now stop the russiophobic bullshit talk to a person who's not telling you that Russia is right, but that you should worry about being lied to by your own media before you worry about other countries telling lies to their people.
