Women and children were the main victims of alcohol-related abuse. To work towards prohibition would mean that the abuse would minimize, if not stop. That is why women's organizations worked for it, to protect themselves and their children from the drunken fathers and husbands.

Back in the 1920, this country was still religious. They viewed the consumption of alcohol as a sin. Also the women's groups thought that alcohol was the reason why men were leaving their families. The women and children lived in fear or were abused by their husbands/fathers when the husbands/fathers were under the influence of alcohol. Hopefully this helps.
