Also, I think there's a sort of filial standard that is very common in the world that says that you might be right, but your elders have thought about things longer so you should listen to them instead of shouting over them. You are also aging, and there are people younger than you to whom you can teach the truth as you see it; more and more of them every day, and fewer and fewer older people. If the old person is right, you're going to lose what they know when they die. Let them get everything out while they still have time. If it sounds like they're full of shit, which they often are, consider the alternative that you may be an idiot. You don't have to make a final decision between the two possibilities now (only provisional ones), but maybe by the time you're old you'll have figured it all out.
