Well sorry to say that link doesn't substantiate your claim. The page it's self doesn't even say Christian. I chose one random link I knew nothing about and guess what, nothing about christians.
There's a common underlying theme that you've conveniently missed, sprinkled among the words of many of these people.
For example:
In 2011 David Pedersen and Holly Grigsby killed four people in a multi-state killing spree. The indictment alleged that the two along with others were members of a criminal enterprise whose purposes included “promoting and advancing a white supremacist movement to ‘purify’ and ‘preserve’ the white race and ‘reclaim our country’ and culture through acts of murder on the basis of race, color, religion, and perceived ‘degenerate’ conduct.”
Of course it doesn't just come out and say "He's a Christian"! A majority of people in this country are Christian and are very, very quick to distance themselves from anyone who acts poorly.
On a different note:
I believe a right wing extremist shot up a Planned Parenthood today, but ironically some on here will soon be extolling his virtues.
