No reasonable person can claim today that the US has any concern for human rights. Except for Israel, the US has by far the worst record of human rights violations during the past several hundred years, far outstripping anything attributed to people like Stalin or Hitler, or even the Japanese.
Those here who behave aggressively [towards Russia] are driven by American culture.
American culture holds that Russia is “bad” simply because it is Russia.
No evidence given; this is a recurring pro-Kremlin disinformation narrative about alleged Western belligerence towards Russia and specifically US Russophobia, aimed at attempting to weaken and isolate Russia.
Negative attitudes towards Russia are not simply driven by malicious "Russophobia", as pro-Kremlin media and officials often say, but often derive from assessments of the Kremlin's own policies.
In addition, this case also exploits the common pro-Kremlin narrative of "lost sovereignty", implying that American cultural imperialism is ultimately responsible negative views of Russia in the Czech Republic. This is a factually unfounded claim that follows frequent pro-Kremlin accusations that pursues a hostile presence and control in Europe.
For similar cases that combine allegations of Russophobia and US imperialism, see here.
