Things either need to be really, really bad and people are done or we need to find what they care about more than being comfortable. I was not always politically active. It took until my late twenties and seeing how bad things can really be. I have been an activist on the human rights front for about a decade. And it only happened because I really saw the issues in my country and continent. But while my family knows as I make sure they know, and some kind of care, it is not important enough for them.
But weirdly. My country had literal neo-Nazis as a minister and everyone with a brain thinks we still do as bids of the same feather and so on. And suddenly my leftist but not active friends became active, online and outside that. It is weird when I have been warning that this is the road we are on for the better part of a decade it took it to happen for people to take action. Thankfully we are still solidly democratic so this might work. At least for a few years.
