What are you talking about? There are Holocaust museums all over the place. Of course they make a big deal out of it.
As for African-Americans. For all the ethnicities, races, religions and so on, there is a hierarchy of hate and African-Americans are always the most hated group of anyone. I've seen it first hand and it's as ugly as anything can get. Those people have ancestors that endured everything the Jews went through and that dislike for a group of people continues today. While you can find the illogical hate everywhere, my neck of the woods, the South, is the worst. I've seen drinking fountains in pairs where one said "Whites" and the other said "Colored". My father has told me stories of African-Americans hung for the most trivial reasons such as not saying 'Sir' to a white man. My own great grandfather killed an African-American by hitting him on the head and throwing his body in the incinerator where they worked, all for not calling my great grandfather 'Sir'.
I worked for a large Aerospace company in St. Louis, Ferguson to be exact, where all the white guys in my office and all the white visitors who were engineers in other offices in the same company, used the 'N' word. No one demeaned Jews or any other race.. Only African-Americans were demeaned. Even though I objected they used the term freely in my presence. We had a black engineer and a white guy married to an African-American wife in our office. Whenever these two were present the 'N' word was never used. I could tell they were comfortable using tht term, very comfortable.
My point is, these people have historically suffered horrifically and they still struggle. I had an African-American friend, an ex running back for U of O, who told me that he was stopped often when he was driving some place.
Their struggle continues and we should all help.
