I am an white male in his 60s and I live on the edge of Birmingham.
I go up to Birmingham city centre about once a month to take photographs.
There are times, as I am walking round the city, that I feel like a stranger in my own country due to the number of Asians, Africans, Chinese etc.
On the other hand I went to Seville a year or so back for a few days and it was a pleasure to walk round a large city and see very few "ethnic minorities".
So it just shows you that depending where you live the "immigration" situation can be a large problem, or something that you are not aware of.
While the whites will not be "wiped out" we already have a situation in Birmingham where about 50% of the population are "immigrants" or descended from immigrants.
We also have areas where 100% of the population are Asian or other ethnic groups, and 100% of the children at the schools in those areas are Asian or other ethnic groups.
So it IS an issue that Europe needs to do something about as the "whites" could be a minority is some parts of some countries over the next few decades.
