um....no, no they didn't.....yes, because they weren't motivated by racism.
Well, the VA tech shooter really hated white people... so not so much.
Adam Lanza's mom was a racist prepper who was stockpiling weapons for the riots she thought was coming. So yeah, he went nuts.
His motives were he was rejected by a white girl....and apparently hated "rich kids" and referred to the Columbine killers as martyrs....he was a loser kid that lacked social skills and felt the world wasn't treating him fairly....blamed others for his failures....it wasn't a racially motivated killing....people from other races were killed.
She was racist? Proof? yeah she liked guns....so what? She didn't do the killing, she was a victim....reports say she was a very nice lady, good mother and member of the community:

ace it....your claim that mass shooters are racially motivated has been, debunked and instead of owning that and moving on, you are now resorting to making up and defaming victims....just sad
