Interesting read. It doesn't mention if he had a girlfriend. Underneath it all is a distraught, disillusioned person who couldn't handle life. Lack of money, jealousy over a race stealing women from him, preventing him from getting one of his own. Maybe Jimmy had a little Jimmy and was spurned at some point in life but he is not your icon of white supremacy and a martyr he will never be. Sorry dude.
What's truly disturbing is that the reason he did this is because when whites are a minority we'll be treated just like whites treat minorities now, because there is no such thing as race and a certain % of people just suck and look for excuses to fuck with others. Skin colour and culture (religion) are easy labels for "others" to target as the source of problems.
