Eh, I look at all this and feel like black activists have been trying to warn folks about these kinds of attacks for years.
Reform gun laws all you want, but until the US treats white terrorists like they treat non-white perpetrators, reform will just be a bandaid.
White supremacist extremist believe they are in a religious war. Their version of jihad that they call rahowa. And they've been in their woods stockpiling, training, and studying. It was only a matter of time before they pursued their goals beyond terrorizing black people. However, it could be that no one would have given a fuck if they had only continued terrorizing black people.
