The “kick up the arse” doesn’t work. You’re just going to make people get defensive. You being rude gives them an excuse to not listen to you - now they can strike you off as a madman radical and move on with their lives.
This person was just advising to not get overwhelmed with anxiety and panic for the future because it’s just going to make the present suck before that future is even here. They never said “don’t take any action at all” or “it’ll all magically be okay”. Going to that person to try and overwhelm them with anxiety and panic for the future and calling them names for not being overwhelmed with anxiety and panic for the future isn’t any kind of rhetorical “tough love” thing you’re trying for it to be - it’s just a dick move.
Trying to overload people with fear doesn’t work. It’s actually a denialist tactic, when your brain is so overloaded with fear it can’t function with it, everything turns into a blurry mess as a self defense mechanism. You stop thinking about it, that’s what most conscious people have done. Very, very few people have genuine faith and trust in today’s political authorities. But regardless, in that state it’s very easy to fall for a counter narrative just to be more calm with your life.
Also, I’m not a liberal. Not every country has an organized and effective radical left. In here the most radical leftist parties are leninists who only sit on their asses writing articles on websites that look from the 90s about how we should support ISIS in their anti-imperialist struggle and how everyone but them is a liberal. I focus on improving and sustaining my own community.
