Who is pro-mass illegal immigration? I don't think I've seen anyone on this thread propose opening the borders, or even stating that what happened in Cetua was fine and dandy, just that it is not a risk to GB and that Spain and the EU are managing the situation, so the hysteria is unnecessary.
I'm not pro-illegal immigration; I just understand that illegal immigration is complex and should be dealt with humanely, safely, and with nuance.
I'm aware of the issues with hotels housing large numbers of immigrants; I'm also not blinkered enough to believe this is only because of cultural or religious beliefs. If you took a large group of disenfranchised young white men and shoved them in a hotel with less than £50 a week to feed and clothe themselves and no opportunity to find work for an indefinite length of time, the same issues would occur. That doesn't mean we should tolerate these young men behaving in this way; we need a better system than abandoning them in hotels for months on end. Those who do commit crimes should be punished in accordance with UK law.
I'm aware there is a small subset of muslim men who would like to bring problematic aspects of their culture to Western Europe. I'm also educated enough to know this will never be tolerated. Sharia law is not and never will come to the UK. I'm also aware that most muslims do not want this; the reason they come to Western Europe is to escape these types of regimes.
My experience of the small muslim population we have locally is that they are charitable, generous and respectful of local culture despite the shocking level of misinformation thrown at them (looking at my mother, who is 100% convinced the government has given her Afghan neighbours a free BMW). Our local Mosque does more for this town than all the CofE and Catholic churches put together. Whether you are white, brown, black or yellow with purple polka dots, if you go to the Mosque in need, they will help you.
NB: My mother's Afghan neighbour works for a large IT firm; his salary paid for his BMW.
