Being furious at not being able to finish an argument I started for at least a week when I back to school.
The worst thing is I'm partly wrong though. The guy was doing the leftie argument that racism is discrimination against someone on skin colour, nationality, beliefs (wtf), religion and culture.
Now (retardedly enough considering someone from Germany for example, is of the same race as the average Brit) discriminating against someone because of their nationality is classed as racism in British law.
However, if you can convert to a lot of religions how the hell does it have anything to do with the concept of their being superior and inferior genetically different groups.
It sounds like someone wanted to sound fashionable and intelligent but they hadn't heard of concepts like xenophobia, Antisemitism , religious hatred and so on.
There really should be a separate definition and term for discriminating against a specific nationality as well (maybe there is idk tbh).
