I am appalled at those that pretend to fault Tamar for not doing her research -obviously those commenters are the ones whose research is inexistent. The inclusion of non-Jews in the Yom HaShoah commemorations can be polemical (see e.g.: http://www.myjewishlearning.com/holidays/Modern_Holidays/Yom_Hashoah/Greenberg_Observances.htm); however to my knowledge there is no special provision restricting the commemoration to Jewish victims of the Shoah in the Israeli law (since that's what some of you are using as a reference, apparently) establishing this commemoration -please correct me if I'm wrong. Tamar's post seemed to me to be eminently non-controversial: she even wrote "It’s natural that we should focus on the community that is closest to us, and that we would fixate on our own families and the stories of those we are familiar with." This post seemed to me to be a decent memorial -I am quite shocked that the comments have defaced it.
