I think the problem comes when you end up in bubbles online. Plus being online allows you to be completely different (sometimes) than you would be in person. I think people maybe had more respect for others when arguments would happen in person vs now where everything is in an online echo chamber, and on Twitter/Facebook comments where nothing constructive is actually ever going to happen.
Hell, this forum is a great example of that too. How often is anyone's mind ever actually changed here?
Its not about changing minds, its about maturing the adults around our society.
Like this thread, may have reminded a number of people, especially lurkers, that they should be keeping better tabs on their HVAC and pipes to avoid them bursting. Or maybe it made them think of their Aunt and they texted her to remind her to trickle her faucet when temps are below zero.
When you cut people's bullshit and speak sense, people have no choice but to hear it and see how effective it is in solving problems.
This influences them to listen to more people like you, do things like what you said because those things were effective.
Literally someone has to set examples of positive sensible adults who value and espouse competence over bullshit, just to get the message to people of a better way to be, or all they see is the horde of texting-while-driving zombies and join in.
And nothing we say will directly nor immediately break up that horde, but bit by bit if you force people to acknowledge that competence and effectiveness and efficiency and empathy are far superior to word salad and societal vaporware, some of them will have no choice but to change, even just a little bit, and begin an erosion of the current Idiocracy status quo.
Nothing in this world cannot be ground down by erosion.
