No, the many, many individuals who donated to Anthony's cause and make posts justifying the murder of a White high school kid because of their animosity towards all Whites as a collective are "making it racial." And the family of the killer hiring a race baiting activist and child abusing criminal to be their spokesman in order to play the role of victims when their kid murdered a White kid is "making it racial."
I don't think anybody is saying the stabbing itself was racially motivated, but the widespread justification of the killing out of a desire for racial revenge (read the comments on Anthony's fundraiser if you haven't already) is entirely about race.
