However, saying that this killer was Muslim would upset the MSM lie that Islam is a "religion of peace."
I think the ones who are trying to deflect attention from a possible religious explanation -- and I'm not saying this IS the explanation -- by bringing up Columbine are missing the point.
If I recall correctly, Harris and Kebold were dabblers in the Goth culture, which, like radical Islam, also devalues human life and glorifies death. Ideas have consequences.
If this young man had been taught that non-Muslim Americans were the equivalent of pigs and monkeys, that the ultimate fate of infidels is death, and that by dying in the act of Jihad he would get him 72 virgins for eternity, then, it seems to me, that is a relevant consideration in the search for his "motive."
