Agreed. I was happy for decline of world population but seeing the rise of anti-envirmentalism makes me think that child-free people might be more inclined to be selfish. After me, the deluge!

Edit: to be clear, I see possibility of selfishness as a side-effect of being childfree, not a corelation.

Interesting correlation, if one doesn’t have offspring to “leave a better world” to why should they care? Hadn’t thought of that before.

Selfish or otherwise unpleasant people can be found in any demographic: childless people, people with children, people over 1.80m, people under 1.80m, etc.

Some demographics certainly have higher ratios of unpleasant people. In some demographics it's even close to 100% (e.g. neo-Nazis).

It's entirely unclear to me if the rates are different for people without children. If they are, then you really need to do better than this kind of armchair analysis that you've posted here.

If you think that simply having children makes one selfless, I recommend talking to like... 80% of the people with parents for five minutes about their childhoods.
