[Q]: You don't need the hyperbole. Discretely being armed to answer the door, or do anything else in life, isn't paranoia. If you need the weapon you have it, if you don't the other person never knows it's there.
[A]: No


[Q]: Having raised my 2 children fully in the Alaska school system there are plenty of ways to corrupt their minds. But some how they straighten it all out and turn into fine adults, although  I  sure did have some doubts at the time. Reproductive education belongs in the public schools. As a teen in the late 1960's no adult would speak of "sex".  I learned about sex from my dim-witted class mates who unfortunately made it up as we went along. A lot of my classmates got pregnant at Catholic high and they got married off to the nice Catholic boy who got them in trouble.  Later on while in college the rate of std's were so high that everyone I knew had "one" at some point and they were on penicillin all the time and they joked about it. It took me years to get to know sex better but the journey there was miserable to say the least and affected my life for a long time. No one at the time told me that sex was fun, that would have helped. LOL
[A]: Yes


[Q]: I agree that humans may always desire some degree of FTF interaction, but I think "virtual" online edu may improve in quality to the point that it is "virtually" indistinguishable from traditional face-to-face interaction.  

Furthermore, if we REALLY want to reduce traffic--unlike rail, and at FAR less cost than rail--we could offer generous incentives to students to increase use of ever-improving online edu options, while doing the same to dramatically increase the number of workers-- many of whom can already do all or part of their jobs online--to "telecommute" from home and/or more decentralized satellite offices.
  
And if we hope to guarantee at least two years of higher edu for all--and do so "tuition free", or at least "debt free"--I think the only way this will be affordable may be to increase the number of students who use online options.  Thinking this will be affordable if everyone attends traditional "bricks and mortar" institutions of higher edu is wishful thinking IMO.
