If you think, they only doubt about elders and not the other stuff, talk with somebody about broadcast. Start with a new one (don't look it, read about ;)). Then go on to the new explanation of the generation. Most of the people you talk to, say, they don't belive, it's BS or there will be soon new light. You don't have to show that you think it's wrong. Only mention new light, hard to understand...
To talk about something like the generation that not pass, and that it's unlogical what they told - I can't imagine to talk in this way 10years before.
Hope to wake up a friend very soon. Or maybe I'm caught after it.
