Adam Lanza displayed no political leanings in the least, the only thing driving him was his own madness. He was a nihilist, viewing the entire world as crap and idolizing violence and mass murderers. He often sung the praises of that one chimpanzee that mauled its owner a few years back, claiming that it was "Striking back against oppression" or something. If I had to subscribe him to any political/ philosophical clique, it would have to be an Anarchist.
Dylann Roof similarly displayed no political leanings, he was just a hardcore racist and also a druggie.
btw, I can recall shortly after the Sandy Hook massacre, one of the DUmmies created a thread intended to drum up sympathy for Adam Lanza by claiming that she had somehow contacted Lanza's spirit from beyond the grave and he told her he was "Truly sorry" for the children he killed.
I guess exploiting dead children's and ethnic minorities' tragedies for political purposes is about par for the DU course.
Well, duh!
They regularly exploit both if they can gain perceived political points by doing so.
