This sort of response isn't acceptable here. I would suggest you rephrase.
> Nobody should be expected to make a personal sacrifice to do the right thing.
A toddler can't be expected to do the right thing, but you wouldn't let your ten year old get away with this, would you? "I can't be expected to clean my room when it's sunny outside!".
I am calling out the normalization of irresponsibility here with a re-contextualization. I am not calling the person I respond to a toddler, nor treating them as one.
So it is totally reasonably to argue for making the right choice the obvious one, e.g. by externalising the costs of bad choices. It doesn't help until there's a majority for it, as you point out, but one way to build public support is to build awareness and criticise the current situation.
Political campaigning and change is how you change things.
Of course, for this you first need to win people's minds. But that's just the first step.
I never claimed that you can fix structural problems by individual behaviour. I claimed that you can't fix them without (some) changes to individual behaviour.
Political change never just happens without activists pushing for it. And in order to understand the space they are pushing for, you need both, leading by example and credibility in asking people to pass laws that mandate behavioural changes.
Finally, I see no evidence for the idea that pushing outside the political sphere can not also lead to societal and behavioural change. Meat consumption is way down among younger people. Car ownership is down, too. This is in all likelihood to slow. But if we ever hope to change laws in cities to get rid of cars where they are not needed, well then having a large chunk of the population cycling and using public transport, and having had a gradual build out of alternative infrastructure due to this chunk of the population is going to make things politically a lot easier.
The same logic applies to divestment. If a large enough number of individual actors divest from carbon extraction, the politics of it change dramatically. And once enough people signal by divesting that they believe that the political change will come (thereby making carbon stocks worthless), they can trigger others into such behaviours.
Arguing for political action always has my vote. It's probably one of the best ways to use your time. But arguing against adjusting your behaviour is cynical and lazy. And arguing against people on here advocating for others to change their behaviour is actively arguing against political action. Because that is what political action actually looks like on the ground.
It will never work from the bottom up even if everyone agrees what the right thing is.
This just ends up with you declaring: It's someone else problem to make me.
That's not pragmatic. Unless you personally invest time and effort into political change to address these issues, it's just lazy and irresponsible.
Just own that. I have adjusted some behaviours and still fall short in many other areas. Never said it was easy. But here is actually an example where it is easy. Take the train and little cost in time and money, while gaining comfort and productive time. And you're saying you can't even be expected to do that? That's just cynical and irrational.
When it comes to what transport mode is best for the environment I basically am a toddler. I don't actually know what's best. I need to be told what's best by one having a prohibitively high price.
I don't even need to claim that it won't work, I can just point to evidence and you can see: it does not work. People are taking the plane because they can afford to.
Today, a lot of people don't take responsibility for their actions because nobody external is telling them to. This is being a toddler. You wait for some parent figure to tell you that you have to do something when you dont want to.
Today, most of the western world are toddlers and its being programmed into us through movies and games as well. Because this is a state of mind that is super easy to control. You end up in consumer mode, wanting things that make your life easier. :)
I might have no responsibility for it, but it affects me. If I choose to cycle to work I'll be a second class citizen on the road while people in cars pass me with little regard to my life. Why would I choose this? Why would anyone choose this? The answer is there is no reason to choose it, so people don't.
