Tell me, what constitutes of implementing Communism?
The only thing that Communism implies (according to its purest definition anyway) is that all property belongs to the government. But alas, we do have private property rights here, as the Chinese economy is Capitalist.
Establishing a dictatorship and appropriating all property comes to mind, just like what happened under Maoist China/the Soviet Union/North Korea, etc. The notion that these were not "pure Communist" states is nothing more than a cop-out, utopian agendas are never and can never be perfectly implemented; the agenda of these governments was explicitly Communist, and everything they did was in pursuit of specific Communist goals, which tend to require exactly the means enacted under the likes of Stalin/Mao/Il-sung/etc.
The Chinese economy is now a mixed economy rather than a Communist economy, but with too much state control to be considered a "capitalist" economy (not even 'state capitalism'). I think "heterodox" economy is the term for such economies.
As for the rest, its like I said; we seem to have drastically different interpretations of "oppression" and "disadvantaged"; the Christians are not currently as oppressed as some groups (such as the Tibetan Buddhists or the Falun Gong), in large part due to the potential international backlash among trading partners, but they are hardly free to practice their faith without unreasonable restrictions on their activities-members of illegal 'house churches' are still rounded up and given at least a slap on the wrist whenever the Communist party wishes to make a point. Also, isn't it still technically illegal for a member of the Communist party to be anything other than an atheist?
Your apologists posts seem to rest on the notion that the Chinese government isn't so bad because things are no longer as bad as they were under Mao; Tiananmen Square might not have been as horrible as the Great Leap Forward or the Cultural Revolution, but it was still an atrocity. Individuals might not be under strict totalitarian control anymore, but they are still oppressed by any reasonable standard.
