You don't seem to have a reason to believe its a hate crime except a belief that it must be and that he is lying about that motive. Which is a pretty wild conjecture.

And? Do we know he actually targeted them or that those were simply unfortunate? Plus not all his victims were Asian women, so? How do you explain the other two? Why did "AsianSlayer1488" as you claim also shoot non-Asians? Did he look up "Asian businesses"? Do you have proof he did?
I bring up the Boulder shooter, mainly because there the shooter was less convenient for you and the victims were universally a single ethnic category, different from the shooter, and yet no assertions of a hate crime were bandied about by you lot.
