During last week terrible things happened in Oslo, Norway. More than 80 people were killed because somebody realized his diabolic plan. Probably for US the 9/11 is a sad day, a milestone of the american history, and I would say for the hole world, but I am certainly sure the massacre of Utoya will be burnt deep in the memories of the Norwegians.
However, either we want to admit or not, in Europe there is a problem, a huge one. US solved more or less this problem, but we should not forget about those segregations in the south of the country. In Europe seems to be a new wave of hatred against your follow neighbor.
Indeed, in the last 20-30 years a huge immigration has started from 3rd world countries and also Eastern European countries toward Western European countries like France, Germany, Italy, Spain, Great Britain, The Netherlands, etc. Of course, the different language, the education, the faith, behavior was mixed on european soil and the diversity, even though it is a nice concept seems to fail. You can just remember the statement of Angela Merkel ...., "the approach [to build] a multicultural [society] and to live side-by-side and enjoy other ... has failed, utterly failed."
Of course, as we claim being a democratic society, we have laws to protect people, but nobody can deny the growing hatred against the others. Is a small seed at the beginning and is just growing and growing and might end up in such acts as I just mentioned earlier. There is no authority or law to stop this. None. I think we should start talking about this issue and we should not treat this problem as a tabu anymore.
