Will our youth fight for globalism and world governments? Nationalism is a pretext for patriotism. IMO only patriots fight with determination.
Some will, some won't. But has anything really changed?
Did many of the "forgotten generation" vote for Kennedy/Johnson and support the Great Society? Yep.
Did the hippies support capitalism? No.
Did lots of GenXers "Rock the Vote" for Clinton and look the other way when he lied? Uh huh.
Was Obama elected twice, with the help of Forgottens, Boomers, GenX, and freshly-minted Millenials? Yep.
Us older folk seem to have forgotten the errors of our brethren in our youth. If we keep (wrongly) bashing all Millenials as the dumbest generation ever, let's not be surprised when Kamala Harris and VP Spartacus take the oath in 2 years. To wit: "you're all stupid but vote for Trump anyway you snowflake" is hardly a great message.
