What they think is simple.
Let us live and work in peace, let our small communities be homogenous white, we tried immigration it does not work.
Leftist policies comming from city bureaucraty does not work.
They want to live decentralized and be governed on a small communal basis and send home all the criminals which have been brought in to destabilize the communites.
Read this case for example where refugees set fires and when the firefighters arrived they have been slandered and attacked, blocked by the refugees who set the fire in the first place.
Many such cases and when someone says anything about it they are beeing gaslight and framed as racists.
