If you want to visit Europe, do it now. In 10 years France, Germany, London and other EU countries are going to be the same hell holes that the refugees and other muslims left behind when they immigrated to Europe.
They won't assimilate, they continue with their 7th century way of life, they just reproduce 7 at a time, live off the government welfare and they and the expect everyone to cater to their backward way of life. Of course the liberals that run the countries in the EU have no spine and will allow the take over of their countries.
Considering this in now almost a daily occurrence in Europe, the term "extremist" doesn't really apply anymore. Unless, of course, there's a whole hell of a lot of so called "extremists" amidst all those "refugees" they've allowed in.
