Sexism

Abraham Lincoln, one could argue was a product of his times. From his views over the institution of slavery, to his rough and rugged frontier soul, he fit the description of a man from his time and place. However, some evidence of his treatment towards women suggests that he may have even been a little bit sexist. There was a situation where he was walking with a women and when they came across some mud, instead of helping her to cross it, he just went about his way. Does it suggest that Lincoln was sexist, or considering his rather unlucky and awkward past with women, does it suggest that he was just extremely oblivious to women around him?
