I will say that Cruz isn’t white supremacist sounding name.
I guess that is a pic of the nut that did the shooting?
Yes. Do you get the point though? You said Cruz isn’t a name you’d associate with white supremacy. Is Cruz a name you’d associate with that face? Surnames don’t matter.
Surnames can be an indicator of place of origin. For example if you someone had the last O’Leary, and that was all you knew about the person wouldn’t you maybe think he could be Irish?
