Some fun fact, the "political extremists" they are talking about are pretty much anyone who dares to be even a centrist. The AFD. Alternative for Germany is pretty much the ONLY party of name in Germany who is actually FOR direct democracy, something all the other parties HATE. Because they claim democracy is what they think is right, and the actual citizens should never really have any decision over things.
The current thread to democracy are the parties who try to ban parties and call everyone a Nazi who dares to be centrist or right wing. As a German, I know what I am talking about. Politics on the last 20 years have shifted to the left so heavily that we are seeing a well deserve swing back of the pendulum.
Let's just indulge this "lonely people" causing it for a sec. If this would be true, MAYBE it's because lonely people spend more time on the internet and actually read and watch alternative media and come to an informed decision about that they want to vote and advocate for. They may detest their culture being replaced with other cultures they never asked for, maybe they want some kind of "Germany first" politics (I just made that term up). Instead of going into war with Ukraine, people want the resources spend on Germany. All the other parties are PRO WAR, even the left and the green party are voting pro war and military intervention and aid all the time. They send our money somewhere else!
And who caused lots of this loneliness? All the parties who they want us to vote for, they introduced draconian covid lockdowns that isolated everybody and put even families against each other. They did way more damage with their insane unjustified BS then covid could ever do!
