Some people might not like what I'm about to say here, but the thing is, men and women ARE different, and should be treated accordingly so, but still respectfully and without discrimination or prejudice. In an ideal world, if a man and a woman have the same job, the same qualifications and do equal hours, then neither the man
nor the woman should have bigger pay packets just for being a 'certain' gender. As such, this is not such an ideal world, and it looks like it'll stay that way for the time being also.
Anyways, as Bingo675 has said, stereotyping people based on their gender really shouldn't be all that desirable of a thing to do, as there will always be a great exceptions to these 'rules'. Women can be strong in many aspects, and men can be weak via physically/mentally/emotionally aspects. I wouldn't expect a man to 'just take it' if an aggravated woman is slapping him around any more than I would tolerate a man slapping his girlfriend around, but I understand that women 'generally' have the more fragile physique and believe that minimal force should be used in most cases (if possible/life threatening situations)
In many domestic situations, while men are more likely to keep quiet about abuse, women are more likely to report it due to receiving far more refuge facilities, more helplines, favour in courts and even more. It's pretty unjust that men are overlooked, but unfortunately, it's known that men
are majorly amongst the number of abusers. The (UK) statistics are that 1 in 4 women experience domestic violence in their lifetime, and between 1 in 8 to 1 in 10 women, they experience it annually. Less than half of all incidents are reported to the Police, but they still receive one domestic violence call every minute in the UK. Key statistics also mention that domestic violence kills over two women per week. While there are men that do suffer and need help, women and children appear to be victimised more often and perhaps do need more help, but that doesn't mean that the victimised men should be left out in favour of the women/children. ALL abused people need help, period.
All in all, it is often an unfair system going on between the two sexes, and tilting the scales in favor of one (while depriving the other) isn't going to work. It never has done (except in extreme patriarchal societies) and it never will either in a civil society. As far as I'm concerned, the only job a woman shouldn't have is being a sperm donor, and the only job a man shouldn't have is being a wet nurse.
Seriously though, the difference between men and women should be respected as they are, and not favoured one above the other.
EDIT: There are some things that men are still in favour for, and still things that women are in favour for.
