Do you mean where whites are expected to become Borg like creatures and pretend that race doesn't exist while every other ethnicity has very race specific groups of every kind imaginable from political & lobbying to social and other wise. That kind of 'insecure whiteness'?
The fact of “white” superiority is in fact: History. The real question to be asked is “Why did the West achieve so much while other groups did not? It is obvious that all races can excel in all fields of endeavor when given the opportunity. And (drumroll please) the Answer is the Biblical Consensus that opened the door to human technological and social progress. Where the (“white”) Judeo-Christian culture fell short, its spiritual reserves and Torah foundation led it to excise those inherited moral failures and move forward to ever expanding freedom and prosperity. It is a Fact, that the white nations were at the center of human progress, but it had nothing to do with the color of their skin. The wellspring of this wonder was the biblical (though flawed) world view of Christianity, enriched and sustained by the Torah: the Instruction for Life that gives mankind the Truth of what is.
