To be honest, I'm not sure that I would have been any different had I been a 19 year old today. I like to think I would have been able to see the truth, and speak it, but peer pressure is immense at that age. They are very caught up in being 'nice and kind and righteous', it doesn't pay to be an outsider in your peer group. And it doesn't cost them much to parrot the mantras, for which they get rewarded heavily with social kudos.
Even adults struggle to stand up to this issue, so I don't blame young people for going along with this, even though it's nonsense. I'm hopeful in years to come they will see that they were manipulated.
