Good points. People like virtue signalling without having to take responsibility to make difficult changes. I think this relates to your article about people who didn't follow your nutrition advice. Just as it feels good to pay for advice, it feels good to loudly shout that you care about the planet. But making difficult changes requires a different process, a different mental state. Protesters get a high from protesting. Making difficult changes in our lives doesn't come with the same adrenalin rush.
