The walls of the echo-chamber have been built up and reinforced for over a decade. No single election cycle will ever pierce through.
These people are lost causes unless a massive culture shift happens. And it's not looking like that will happen in the next decades. You, just like other countries, will have to deal with a growing strong block of far right, young men who will grow up to be far right seniors.
The warning signs started being obvious with Gamergate but they were ignored. The only thing that can be done is preventing the growth of these echo-chambers but the damage is done. It's just like how carbon capture will not solve climate change, only stopping emitting more as soon as possible.
To be fair, people with tumors behind their ears will likely hide it to avoid assholes staring/taking pictures. I don't see many cancer patients attending chemotherapy either because they are wearing hats/wigs.
Still, shouldn't they get cancer on their hands instead? That's the closest body part to your phone at any time on average, isn't it?
