people need to want to open their minds first before anything you say or do can change their views of bitcoin and the technology. and if they already have an open mind then the "knowledge" is already out there to be found and learned, you just have to search for it. for example you can go to bitcoin wiki or other proper sources such as some of the books that are written like the Andreas Antonopoulos book called Mastering Bitcoin and learn more.
a forum is just a place to share your opinion on the matter, discuss things, or ask questions about things you didn't understand. it is not a place to learn the basics in my opinion.
What you express in my opinion is very useful and a fairly good thought, I really agree with your expression. to understand and learn bitcoin or cryptocurrency must begin with the individual's desire, if there is a desire then it will surely find the way. for those who really want to know about bitcoin, of course there are many references that they can look for as the basis for their knowledge of crypto and then they can make this part of what they want to ask or in addition to their insights about bitcoin.
