There is a deep truth that has clearly manifested itself during the
1960's (and its "Youth Movement" and countermovement) and more
recently with all the partisan ruckus (not to mention during all the
times between): the only way to get a civil discourse, whether it be
in politics, science or elsewhere, is to first get all the Baby
Boomers out of the room.
You've also seen it in this group, where the self-appointed police
serve as nothing more than enablers of the self-appointed obtuse
luddites and vice versa.
A few reach the point of Understanding (of this basic truth) and
Transcendence (from the Me Generation's permanent rut of selfishness,
generational conceit, generational self-centeredness, "we're forever
young" on canes, extremism on everything) and leave the room.
