Not according to the shooter - "Police say Mr. Adkisson, an unemployed mechanical engineer, left a note listing his own inability to find a job as one reasons for his attack. He also railed against the Unitarian Universalist denomination as being "liberal," including the church's advocacy for gay rights. The FBI is investigating the shooting as a hate crime."
I agree!
Being a very dark troubled guy doesn't make one insane. Is Stephen King a dark, troubled liberal shooting up churchs?
