That doesn't mean I tolerate old farts shouting at my children for being young. Or excuse shitty behavior in general.

But the default for me is paying respect for the elders. Offering them my seat in the train if there is no other, etc.

But... why does living longer in and of itself command an extra degree of respect?

I offer old people my seat because they'll likely feel pain if they have to stand up for a while, they might fall down if the bus goes bump, etc. I won't be pained by standing up for 45 minutes so it doesn't really come at any cost to me.

i.e. I'm not giving up my seat because I respect old people for being old.

That's not a reason, you're just repeating the question. "Having lived long" is a value neutral statement of fact. How do you derive value from that?

> And are usually more wise in life experience.

So is that your true/only reason, a statistical probability of "knowing more"?

It is a reason in itself.

I don't know if I manage to live 10 years more, not speaking of 50 years more.

Living long is a achievent on its own, not be brought down early by life. Because there is a lot that life has to offer to bring you down.

That requires a minimum of wisdom.

All while at the same time putting everybody who didn't get the chance yet below them. It feels very arbitrary - there are a lot of better indicators than age for that.
