To Forget Or Not To Forget, Is That The Question?

Never Forget! 

What does that mean?  I mean when a person puts it on a poster, or T shirt, or bumper sticker, what is he or she meaning to say? 

It might mean, do not forget the sacrifices of the first, and second, and third responders.  I can buy that.  But I have the feeling that it also means, never stop hating the perpetrators, and their kind.  Or never stop feeling damaged.  In these cases I'm not so sure this is good advice.  Wouldn't it be better to just get over it if you can. 

I think I'll look for a bumper sticker that says, "Forget!"

I'll put it on my bike.
