If someone of white European heritage burns down a synagogue frequented by what you consider people of white European heritage, would you still consider that racist given they’re the same race?

Individual people can be racist in all sorts of kooky ways, like there's certainty individuals racist against white Irish people and against white people from Mediterranean countries. So, yeah, it's possible for a kooky individual to be racist against Jewish white people.

But that's not reflective of society, of systems of social or political power, or of the current cultural epoch. That's just a freak.
