This is very sad. I have tried to put my finger on Scottish culture for years now. The people who knife each other are tragic victims of what happens when a bad culture is allowed to blossom at the expense of proper education. Scottish people hold on to this culture of not speaking properly and behaving in a rather unusual fashion because apparently they are convinced that that is their cultural prerogative. The end result is thousands of very poorly-educated, economically disadvantaged young men who, because of their lack of education and the neglect they have suffered, have no other way to express their despair than to go and fight each other, usually after getting high on drinks or drugs.
These are victims crying out for massive changes and reforms in Scotland. I suspect their voices won't be heard. There is so much about Scotland that I simply detest, and for that reason avoid. The wealthy middle class people in their business suits don't care either. This is a really nasty, intolerant country - I have been ridiculed many times for my way of speaking, and for that reason I hardly speak at all any more, and I have an unusually quiet voice.
