And also to remember how it happened. I see more and more people with an attitude that what happened in the past is in the past and has no relevance now. The potential for another event like the Holocaust is still there, as are almost all of the beliefs that led to it, and I'm not just talking about hate groups, I'm talking about common views held by a lot, if not most, people.
Today is a day to pay our respects to the dead and the survivors, sure. But also a day to reflect on ourselves so that we can prevent anything like the Holocaust from happening in the future.
