well you say no one was objecting during the Vietnam war,
Nope, did not say that.
but can you say for sure if social media was available then as much as it is now that there would have not been objections.
This makes no sense, you obviously are not familiar with Bob Dylan, or Crosby, Stills, Nash and Young, or Muhammed Ali.
On face book there to many objections to count, about Nearly every war since Tony Blair UK prime minister was found to be lying has now been highly objected which is how it should be but that was only 10 years ago. And only because of social media advancing because of social media platforms like face book and YouTube
This is foolish. We have had people who stood for the truth long before Zuckerberg. We also know that Youtube and Facebook are controlled platforms by the FBI and CIA.
Actually back in the days of the dinosaurs we had books, and people actually read them, and they could be published by just about anyone with a few dollars.There never has been a world wide platform for people to voice there views take for instance American soldiers poisoned in the Vietnam poisoned by there own nerve gas left with disabilities.
The Falklands war many soldiers making it known the war was not merited.
It's only thanks to Facebook and YouTube we get to see the pictures and stories that the news broadcasters never had access too and could never show.
