An excerpt from the article quoted:

Yet von Brunn killed not a Jew but an African American -- security guard Stephen Tyrone Johns.

So which community was affected by this weird, virtually suicidal act? Was it the Jewish community or the black community?

The community that was the target of Von Brunn was the Jewish community; the race of the guard killed was mere happenstance. To von Brunn, the guard was merely an appendage of the Holocaust Museum. His criminal scenario was to affect the Jewish community, and any felony (including murder) flowing therefrom should (and is, to my understanding) considered under the original attempted felony.
