The Chinese are pragmatic and unsentimental to a degree that is difficult for Americans to appreciate. Especially I think to feelings-obsessed liberals.
What you meant to say was that “Chinese are cold and inhuman to a degree that is difficult for Americans to appreciate.” It's true. Most Americans don't “appreciate” cold and inhuman people, but “feelings-obsessed liberals” otherwise known as ‘socialists’ do.
They are very “appreciative” of social engineering of the type that produced China's One Child Policy which is about as cold and inhuman as social engineering projects get.
Only Mao's Great Leap Forward which starved millions to death or Stalins collectivization which did likewise could be considered more cold and inhuman.
