He glosses over a lot such as:
___ that History is rarely objective. Choosing your history to conform to your ideology is dangerous no matter which ideology is yours.
___ that the "traditions" of the past have included some pretty horrific things (see above on history). It is WRONG and IMMORAL to paint the past and past "traditions" as absolutely better than what we can aspire to. We should learn from the past, not slavishly imitate it.
