My family (most of whom fled the Shoa or were caught up in it) and well-known facts are not revisionists.
The fact is that while most "pure-bred" Jewish people like myself and the bulk of my family were screwed, the situation for mischlings was much more complex
See "reclassification procedures" here:
"The process was humiliating for the (grand)mothers who had to declare in court that they had committed adultery. The petitions were successful in the majority of cases. The high success rate was a result of several factors. First, some lawyers specialised in such procedures, prepared them professionally, and refused hopeless cases. There was no danger in the procedures because failure did not downgrade the classification of the litigant. Second, usually all the family members cooperated; including the sometimes still-living disputed (grand)father. Likely alternative fathers were often named, who either appeared themselves in court confirming their likely fatherhood, or who were already dead but were known as good friends, neighbours, or subtenants of the (grand)mother. Third, the obligatory and humiliating body examinations of those under suspicion were skewed by stereotypical Jewish perceptions. Expert witnesses would search for allegedly Jewish facial features, as conceived and understood by anti-Semites. If the doubted (grand)father was already dead, emigrated, or deported (as after 1941), the examination searched for these supposedly "Jewish" features in the physiognomy of the descendant (child). Since anti-Semitic clichés on Jewish outward appearance were so stereotyped, the average litigant did not show features clearly indicating their Jewish descent, so they often documented ambiguous results as medical evidence.[16] Fourth, the judges tended to believe the accounts of the (grand)mothers, alternative fathers, doubted fathers, and other witnesses who had endured such public humiliation. They were not recorded for earlier perjuring, and judges would declare the prior paternity annulled, ensuring the status improvement for the litigant. The effective assimilation of Jews and Gentiles of Jewish descent into their Gentile (and Christian) surroundings made matters much more complicated than the Nazis had anticipated; widespread corruption, and lack of ethical moorings among many Nazi leaders, frequently gave way to bribery, extortion, and other subterfuges concerning documentation of who was, or was not, a Jew."
