One Lawrence Auster seems to have arrived onto the same point that your humble servant also has repeatedly made, both on this fine forum and elsewhere:
In my view, the biggest single factor driving whites to national suicide is their false guilt over black inferiority. Because whites believe, as liberalism has taught them to believe, that all groups have equal inherent abilities, they conclude that the actual backwardness of blacks must be caused by something that the whites are doing to them (or failing to do for them). The result is the paralyzing racial guilt which makes whites feel that they have no right to defend and preserve their civilization, no right to defend and preserve themselves, but that they must instead self-sacrificially open themselves to nonwhites, a self-sacrifice that takes numerous forms, including naivety about black violence, denial of the tyrannical and murderous reality of Islam, and acceptance of mass Third-World immigration. Therefore, as I began saying in the mid 1990s, if whites could see the truth that black incapacity/dysfunction is not whites' fault but is inherent in blacks themselves, it could literally save the country, by freeing whites from their suicidal guilt.
The truth about racial differences in average group abilities and their partially heritable nature shall set us all free. Including the Blacks.
