I think a great majority of the general public has forgotten.
Not me. I'm reminded every day I wake up and don't have a job to go to. It's VERY real and it's not that I don't think about it, or that I don't want to pretend it doesn't exsist or never happened. Those were MY co-workers, MY airline's airplanes, believe me, I remember. I remember every day that awful feeling in the pit of my stomach as I suddenly realized my life had changed forever. I would only come to realize in the months afterwards just how much. Watching other AA F/As at the airport, they're going about their day like nothing has changed (though in retrospect, their lives have all changed too), while I sit on the street furloughed after 7 years of service to AMR.
So no, I CAN'T ignore it, I DON'T pretend it never happened, and believe me my little world is anything but happy right now.
I just don't want to watch a movie about it. Ask me again in 10, 20 or 40 years, and my answer may be different. But not right now.
