Answer:
the holocaust was a mass genocide of jewish and polish people during WWII from 1941-1945. We remember it because it was a horrible event during a war that killed millions of innocent people. Victims couldn't do anything but hope, most died or were forced to work until they couldn't anymore, then killed. we can honor their voices by looking back into the past and making sure nothing like that ever happens again. the people who didn't agree with this discrimination protested, although they didn't work, we can learn that protesting is not always enough to truly change something, you have to work with the law sometimes.
