He's not comparing Lien to WWII. He's saying that people have to speak out against injustices and listing real events where people either did or didn't speak out. He's picked really big events but he could have told some story that began "in the office last week.."
Now I agree with you that you can't compare current injustices that speaking out on will help remedy to complaining about what you perceive to be a past injustice that nothing can be done about. However I suspect he sees it as an ongoing issue, money versus people so it's not a single incident solely. He's bitching about the B's as happens here all the time, it's just he's focused on one incident and rather passionate about it. That most people don't give a fig or agree with his interpretation makes him easy to ridicule.
