Explanation:

More and more Europeans in more recent times have started to see the immigrants as a threat. There are numerous reasons as to why some people feel that way.

One reason is that they think the European culture is getting diluted because the immigrants are bringing in their own cultures with. Apart from bringing in their cultures, big portion of the immigrants in more recent times do not want to assimilate into the culture of the host country, and very often they create their own communities, where lot of people don't even know the language of the host country.

While most of the immigrants move into Europe in order to have a better life, some of them have other intentions. The terrorist organizations often use the migration waves in order to infiltrate their own members into a country where they want to perform an attack. This has led to much increased number of terrorist attacks, so more and more people have started to see the immigrants as a big safety issue.

Some of the Europeans also feel that the immigrants are taking away the jobs from the natives. The main reason behind this opinion is that the immigrants often agree to work the same jobs as the natives but for lower wages. The businessmen understandably prefer cheaper labor force, so they often prefer the immigrants, which in turn increases the unemployment rates among the natives.
