Discuss the possible motivations for the attacker at a gathering of Republican country western supporters, and address concerns about name-calling and attitude.
Just maybe this guy was anti guns.  Maybe he was angry that more controls were not enacted so he decided to attack a gathering of mostly Republican country western folks?  Who knows?  Your speculation may be completely wrong and so may mine.  BTW your name calling is repugnant, ignorant and ill-spirited.  You might want to check that attitude at the door with your weapons.
