vaama sva-bhaavaa

Asvatthama proved himself to be an unworthy son of Dronacarya or of a briihmana, and for this reason he was condemned by the greatest authority Lord Sri Krsna, and yet a mild woman could not withdraw her natural courtesy for a brahmana. Even to date, in a Hindu family a woman shows proper respect to the brahmana caste, however fallen and heinous a brahma-bandhu may be. 

But the men have begun to protest against brahma-bandhus who are born in families of good brahmanas but by action are less than sudras. The specific word used in this sloka is vama sva-bhava, mild and gentle by nature. A good man or woman accepts anything very easily, but a man of average intelligence does not do so. But anyway, we should not give up our reason and discriminatory power just to be gentle. One must ha e good discriminatory power to judge a thing on its merit. 

We should not follow the mild nature of a woman and thereby accept that which is not genuine. Asvatthama may be respected by a good-natured woman, but that does not mean that he is as good as a genuine brahmana. SB 1.7.42
