It's nto so much a fact as a detail. If the concepts of genocide and persecution can pertain to nationality and religion, as well as race - your differentation changes nothing.
True, but that does not detract much from the nature of the problem or its effects.
But you really dont understand what racism is. I would sugest educating yourself on that matter.
It is not a differentiation. It is something you clearly dont understand. Making fun of Scots in this instance is not racist and not persecution and not genocide. It is simply that, making fun.
Please try to be PC with coherency and logic.
