As with most of the Bible it seems, this part isn't without a difference of opinion. Many folks maintain this passage is a metaphor, not a literal prescription for violence.
Indeed: it certainly seems that way to me -
"Do not think that I came to bring peace on the earth; I did not come to bring peace, but a sword. For I came to set a man against his father, and a daughter against her mother, and a daughter-in-law against her mother-in-law;
and a man's enemies will be the members of his household. He who loves father or mother more than Me is not worthy of Me; and he who loves son or daughter more than Me is not worthy of Me. And he who does not take his cross and follow after Me is not worthy of Me. He who has found his life will lose it, and he who has lost his life for My sake will find it."
...although I think it would be a bit unfair to blame Jesus for women not getting along with their mothers-in-law.
