Thing is, which area do men receive poorer treatment than women? I know the family courts are brought up a lot but thats not based on sex, it goes on who does the majority of childcare...which just usually happens to be the woman in most cases...so yes, women get custody in most cases. Like, if me and my husband divorced tomorrow, he would 'get the kids' because he gets up with them each morning, he takes them to school, he does most of the childcare.
Now if we were a more 'traditional' (read old fashioned

) family where I did the childcare and he worked, then I would probably 'get them' and would also generally get child support awarded (which is for the kids, not the parent)
Obviously if there has been abuse or something then who does the bulk of the childcare is disregarded though so that the kids are safe. But our family courts (not sure about in other countries, am talking about the UK) are definitely not this 'award custody to the female' type thing. Its about disrupting the childrens lives the least.
I am all for fighting for things where men are actually genuinely disadvantaged. Just it seems, I cannot actually think of one of these areas. I don't think anyone should be treat more or less favourably because of their sex. Though there are some areas of life where sex matters (things like sports, prisons...anywhere where biology is important)
