Got Milk?

I often peruse the social website Digg.com, and there was a link to an article entitled 10 Movie Endings Spoiled By History. Immediately, I thought of "Milk". I was standing in-line to see the Harvey Milk biopic with a friend when a woman and I began discussing current events (California's Prop 8 had passed a month prior). She said something like "this movie is culturally relevant to our times." Apparently it wasn't as relevant when it took place in 1978: off-the-cuff, I mentioned that Harvey gets shot. Before I continued with his death, Dan White's "twinkie defense" and his suicide in 1986, she quickly interrupted, "I didn't know that. Don't tell me anything else." For real?
