"Islamification" happens everywhere and it's nothing to be afraid of; it's just a new culture integrating with western society. It's only an issue if you're a redneck or, as some alarmists would have you believe, extremists set up "sharia neighborhoods" in your area, which is against the law to do anyway lol.
The UK has a lot of immigrants yes, but the people who say that someone is racist for using the border as an excuse to leave probably doesn't understand that a lot of the immigrants that come to the UK come legally through proper channels (if they're overseas immigrants), or are just economic immigrants taking advantage of the EU's free movement. Some people leave their relatively safe, but terribly terribly poor, countries to go the UK and that's what the brexit people played on in their campaign strategies (well, from the ads I've seen on the net).
These local (to Europe) economic immigrants will be able to settle in remaining EU countries so I wouldn't feel too sorry for them, they'll still end up in a better position than back in their home nations.
But yeah, everyone's markets are crumbling. GG UK.
