The big problem is people tend to look at history as a singular event, or the final consequence of a series of events.

When such events are clearly ongoing, people roll their eyes and say you're overreacting. Then when it all ends and consequences happen, people say now is the time for healing, nobody could've foreseen this, and it's too bad nothing could've been done.

It's the same as being sober and trapped in a car with a drunk driver and their drunk friends. To them, it's fine. They're comfortable with what they're doing. You're the one being annoying for complaining. But their every action is not only endangering you and themselves, but it's endangering people on the perimeters who don't even know about the crisis that's happening within that 2 ton box. Some can see the swerving from far away, but there's nothing they can do. The only hope is the passenger trying to reason with an angry drunk to pull over, but it'll never happen. They'll just get more pissed off and drive more erratically to mess with you and to get some laughs from their friends. So it's a struggle between closing your eyes and hoping it's over soon, or trying to fight back and hope you can stop them. But neither option is easy and both shift the responsibility to someone other than the ones causing the chaos.
