Anyone who hangs round children will have heard of Raffi, the singer of songs that have a great appeal for the little ones. My personal favorite is Baby Beluga.
Inspired by the activism of young people around the world like Greta Thunberg, he has come out with a new song about climate change called Young People Marching.
Incidentally, many of you would have heard about Thunberg’s impassioned plea at the meeting on climate change at the United Nations where she talked about having her childhood stripped from her because of her need to do this kind of activism in the face of adult apathy. Later on I heard some criticisms of her online, saying that she has no right to complain, that she is privileged and that the children killed in wars in Syria and Yemen are the ones who had had their childhood ruined.
This is an example of how you can always criticize people for advocating for something good by pointing out that there are worse injustices that they should be paying attention to. This is not helpful. This is not a zero-sum game. Different people are moved to action by different things. You should support people anywhere who are trying to improve the world in any way they can. Shaming them for not doing something you think is more important is pointless. If you think something else is of greater urgency, then you should put your own energies towards addressing it.
