In fact, people in the US are only free to yell at the American leadership in Soviet jokes. A case in point was this June in Los Angeles, when a police officer knocked a protesting woman with a megaphone to the ground and then hit her.
This...is such an incredibly stupid and invalid argument. I can't even...
You see, that would never occur in the RF. Meaning that it would be impossible for anyone to get that close to Adolf Putin's car - not even to Adolf Putin's dog's car. The Tzar has been known to stop and clear traffic from several streets in Moscow when he decides to travel by car.
The argument itself is, as you say stupid. This guy is fighting a lost battle trying to compare the limits to liberty in US or Europe to the despotic limits to expression and the extent of the repression in RF.
