how is there no evidence? you can see observable differences in the way men and women make decisions. and if you're going to say that that's just due to culture or society, there's probably even less evidence to support that.
neuroscience doesn't seem like bullshit science to me, and is it really that far-fetched to say people with different brains are going to make different actions and decisions?
Our society is slowly losing its morals. Also the expansion of the welfare state has allowed women to marry the government and men to abandon their parental responsibilities.
