I think that guilt plays no part in mindset of your average, well-off westerner. It is them mostly trying to raise their personal standards up a notch. They are just striving to better themselves and in their case, living in secure environments, they are projecting their reality on everybody around them while simultaneously trying to raise themselves above already high standards they now hold for everybody. It is hypocrisy at its best, because despite trying to be nice they are again creating a gulf between themselves and those currently bellow them. That would explain hatred children of immigrants feel towards country they are living in. It embraced them to a point but is still sending signal how they aren't on equal grounds.
So yeah, whoever is projecting that white guilt bullshit is actually massive hypocrite and believes he's better than everybody else. I figured this myself through introspection...
