There are 90,000 Asian Americans in Oklahoma. There are over a million in Texas. And more than half a million in Florida. Certainly enough for a pre-mediated act of political terrorism to find a target.

You're constructing a false dichotomy where you assume all Red counties are rural, white, and low-population. That's definitely not true outside the coastal states. If the trend is being primarily driven by Republican voters, the Trump-stronghold of Houston (which has one of the largest Asian-American populations of any American city) should be a hotbed of hate crimes. Yet far more seem to occur in San Francisco. Clearly there's an x-factor that goes beyond Trump.
