A psychiatrist has warned that Germany faces a “time bomb” as a result of the mass migration of young men who have “crazy potential for aggression”.

“This is a time bomb,” Christian Peter Dogs said of the decision to open Germany’s borders, in an appearance on the Peter Hahne talkshow on ZDF last month, explaining that psychiatry has found people’s temperament and personality are usually fixed by the age of 12.

Stating that migrants “can’t just ‘be taught’ to understand our values”, he said that classes on how to behave in Germany were unlikely to have much effect, adding: “You have to accept that.”

“There are people who have crazy potential for aggression because they have grown up surrounded by war. They have learned to fight and don’t even know the meaning of living harmoniously,” said Dogs.

On the Peter Hahne show episode — the topic of which was “the power of fear” — the psychiatrist said the biggest mistake politicians are making now, with regards to the migrant influx, is their response to voters’ concerns on the issue.

People are “neither ‘far right’ nor anything else”, he said, noting how critics of mass migration have been pathologised as “bad” and “far right”, whilst reports of problems with regards to the newcomers’ behaviour have been suppressed.

Dogs, who directs the Max-Grundig psychosomatic clinic in Bühlerhöhe, said people are “genuinely afraid and feeling insecure”, reporting that his clinic treats a large number of people suffering from severe anxiety disorders who feel too afraid to leave their homes since the flood of migrants.

“These people feel completely betrayed by politics,” the psychiatrist said, stressing: “It is vital that politicians take citizens’ fears seriously, because fear is a natural emotion that we are pre-programmed to feel, and politicians are not supposed to lead us into danger.”

Since 2015, when more than a million migrants entered Germany at the invitation of Chancellor Angela Merkel, the government has embarked on a war against online “hate speech”, with police conducting raids on the homes of people suspected of posting comments critical of migrants to social media.

The crackdown on free speech has not been without controversy, however, with the government receiving criticism after its partnership with former Stasi informant Anetta Kahane was revealed.

Dr. Hubertus Knabe, a Stasi expert and academic who specialises in Communist political oppression, was amongst voices who slammed the government for working with Kahane, saying she was unfit to lead any task force charged with censoring speech online.
