I dont think plagiarism is just a
Internaional Student thing, but they do take it to a whole different level.
I am sure as a Student, we have all see or even been part of plagiarism. The difference is that while others may look at your work, question why this is done this way, think for it ( hopefully ) yourself , and try to rewrite it in likely much worst adaptation of it. ( Since the level of understand is usually quite different ) With Copying in few places.
These International Students's plagiarism is basically simple copy and paste editing. It is so bad that even spelling mistakes are the same.
And when you question why these spelling mistake and grammatical mistakes are the same, you will likely get an answer that is because it is how we use the English languages, any further discussion on the subject will likely be countered as oppression, or racism.
The worst thing about it isn't actually the plagiarism itself. It is like Software pirating, a lot of people used to do it. ( BitTorrent, FTP, or if you are even older passing Disc with Code around ) But at least those who committed those wrong doing knew they were wrong. ( Or at least I hope ) These international student often does plagiarism with no sense of guilt or wrong doing, as it is the norm back in their home country. And if they get caught surely some donation would smooth things out. They will think why everyone does that same thing and how unlucky he or she was to get caught.
Now if you think back about all the issues, and instead of happening in a small place called University but in a much bigger world of business and Cooperate, you may see what the world right now are having lots of disagreement.
