How do you handle racist family members?

At my family Easter, I was blown away by the amount of ignorant racist comments I heard from my aunt, my mom and my brother. I can absolutely not believe that anyone in 2007 would think the things they said, let alone say them out loud, and I really cannot believe that I share a bloodline with these people. I looked at my husband in shock and we both tried to handle it as best we could, explaining that we shouldn’t say these things in front of the young children, we need to teach them tolerance and correcting their misinformed facts about immigration laws but it just went right over their heads, as any comment that isn't in complete agreement with them is ignored. I am at a loss of what to do. Normally I would disregard bigots completely but this is my family, as ashamed of them as I am. How do I handle this? It breaks my heart that anyone could feel this way.
