Parasite is really just a poorly defined value term for what we innately deal is the most morbid strategy of life. Carnivore, herbivore, parasite, omnivore, and sanguinivore(dunno actual term) are all really just sliding value terms viewd from a sliding perspective between pure selfishness and a golden rule standpoint.

You might say carnivores and herbivores exist!
The truth is virtually all herbivores are documented eating meat and even lions chew grass sometimes. then you say omnivore! But then we find that there are actually some animals that gain sustenance from minerals like worms that also get sustenance from animal and plant matter.

The truth is, "codification fallacy" is the definition of "subjectivity" and "enculturation" is the definition of "subjectively contagious subjective agnosia."

寄生虫学是研究生物的一个不完善的分支。为什么?因为当我们考虑那些从定义上来说是寄生的东西时，我们通过将它们与其他不是寄生的东西进行比较而失败了。苹果、桔子、玻璃和破窗户等等。一般来说，当蚊子只是在寻找午餐时，我们认为它们是寄生虫，嗯，正如repo man所指出的，嗜血动物(或任何实际的术语)。严格地说，水蛭也是一种寄生的吸血动物，但在这里，它们只是在寻找食物，并准备好从可用的资源中提取食物。从社会学的意义上说，“寄生虫”，适用于某些人或群体，有点用词不当，但我们最好不要诉诸于脏话。所以，我们习惯把各种生物体，微生物和病毒称为寄生虫;病原体或疾病载体，因为它们会导致我们生病和死亡。因为，总的来说，它们没有什么有用的特性，我们就把它们一笔抹杀了，想办法更好地保护我们自己，处理我们的害虫。 When we do the same with parasitic humans, we have always already useful justifications for so doing.
Film makers are all over this when plying their craft. They know their viewing public is always ready to buy a thrill. Anti-heroes are better than no heroes at all.

Let me say this film is a load. Leslie's teaser is exactly that. Don't see this film unless you are ready for deep disturbing action, motive and thought. Therein you will find a clear window at the collision of sociological world views that is Korea.

It's stark that the US Gini coefficient is harsher than South Korea's if so far less than South Africa's. Something in that starkness tells me that income disparity is not the whole story here, if even the story at all.

I think instead it speaks to family, love, respect and desperation. My candidate for true parasite is Namsoong, but we are at a cultural cleft that I can't bridge with my limited Asian purview (and I grew up in Japan... once a gaijin always a gaijin.)

Kim's decision is the key to the whole thing. Ki-woo's tribulations are a pretense for his father's transformation. Where eastern confucianism meets disparate capitalist excess is the backdrop. To take this movie in the window of income disparity is a Maoist take not supported by the plot, action or characters. That is not to say income disparity doesn't contribute to the story or isn't a problem.

这里的社会寄生虫是朴。他无法表达自己对妻子的爱，让金在印度突袭前做好自己的工作，并不断谈论越界，这显示了他的寄生本性，但就像我之前说的……寄生虫有一个东方和共产主义的含义，我在我的心灵中找不到。

Good film... can't recommend it to those who can't take gruesome detail.

Confucius over Mao every time when talking about anything Asian.

Well, I did not say PEOPLE were vermin---somehow you read that into my prose, or did you? Your question sounds like you did. Sorry my meaning was muddy or not well-taken. I do try to keep things as brief as possible, but words are difficult to manage sometimes.. Let me give another example. I have thought that Utilitarianism and Pragmatism are akin to one another. Pragmatists are (allegedly) interested in things which are more useful, rather than less (Rorty). Utilitarianism, as a term, implies that a thing (or a class of things) has 'utility' or is therefore, useful. Now, it seems Jeremy Bentham was considered the Father of Utilitarianism, although it is now pretty difficult to find his writing, while it is much easier to find those who have written about him. It is also said that his writing was difficult to understand and that this is one reason why he is not commonly read. I do not know right now because I have only been able to read those things others have written about him. The upshot of all this is that the Father of Utilitarianism: a. did not know what he was talking about, or, b. could not express it, or c. both. So, as you know, words may be misunderstood or misinterpreted, whether spoken or written. This makes philosophy difficult. Especially when terms are not well-defined and/or their meanings not well-agreed upon. I don't expect this clears anything up. But, if it helps, I can say I tried. Merry Christmas!
