I'm not sure that's particularly true.

And it still doesn't come close to justifying taking away someone's input to democracy. I find all these discussions massively distasteful.

Also short-sighted because they tend to assume that the age cohort making the claim have more stake in the future, are all of one mind, are thinking long term themselves, or are generally going to do things better. None of these things hold up to much scrutiny AFAICT.

Claims about "all" are not useful and a distraction from useful understanding of human behaviour. People, like any animal, as a rule, act largely on self-interest. That is with a broad definition of self that includes family --specially offsprings, and larger "identities" like clan, village, city, country, race, creed, religion, and so on.

In which case the entire conversation is moot.
