Some people find the idea of engineering and/or mathematics intimidating. If approached in the right way, it will 'click' for them, or at the very least their fears can be assuaged (allowing them to pursue higher learning). I take two issues with your posts here:
1) From your posts here, your approach sounds like you want to 'beat some engineering fundamentals into them.' You say that you've mentored others, so I can't believe that this is actually your approach, but your posts come across this way. This may be at lease some of the reason that people are reacting the way they are to you.
2) You seem to be lamenting the fact that some people will work on these kits, and never go further with the 'higher learning' aspect. This is to be expected. There will never be a way to convert 100% of those curious into the One True Path of Engineering Enlightenment(tm). At the very least, the people that only dabble will get past the idea that all of this 'technology stuff' is some sort of voodoo magic that the majority of the population seems to believe.
