A Taiwanese Presbyterian congregation. I think this could be intended to scare minorities away from the polls, though I do not know the voting patterns of Taiwanese Presbyterians. It is a page right out of the fascist playbook. The shooter was asian, as were the victims, so there may be some completely different motive. Stay tuned.

asian christians are generally hated by non christian asians. As they should be.
I definitely think an incident spurs on rabid haters to action. Then we have these clusters of copycat incidents.
Perhaps a deranged copycat (sadly, the first of a few) but there is no apparent hate motive as yet.
