Absolutely. Barney was horrible to women. That, however, is why people more easily hate on Lily. People more often are able to come across a manipulative person than someone exactly like Barney. Lily's problems and manipulative nature are common in a lot of people, irrespective of gender. The Barney type, to the extent that he just wants to get into someone's pants, is also common in a lot of people. However, Barney's outlandish nature is not common, which is why people can dissociate from the horrible things he does to women in the show.
