An even worse excuse is to include her just because of a conception going around that there is an open female quota that needs to be filled. A person who has never heard of a quite influential and recent 20th-century figure like Ho Chi Minh is almost guaranteed to not know a thing about Trung Trac, a figure with barely any historical record, other than the fact she was a woman, and then the typical sound-bite judgment along the line of "communism - trash, woman - good" after 10 minutes of googling and probably reading the first 2 sentences of a Wikipedia entry is probably the cherry on top of just pure ignorance.
