No problem about my name - it's not real 
I'm not being aggressive. A bit defensive maybe, but then we all try to do the best we can for our children, and people we don't know generalising and suggesting that we have caused harm to our children is bound to hit a nerve.
There is little point in saying anything, as you just keep saying that 'it is your opinion', so we can get nowhere; but Equal Opportunities is not gender bias. It is giving the job to the best person, regardless of gender.
If an organisation has a large discrepancy in the number of men/women/people of colour/disabled people whatever in particular roles, then they will very occasionally make that right by encouraging particular groups to apply.
It is many years since the LP did that, and when they did it was to redress such an imbalance, which was needed. After many years of sex discrimination, it would have taken forever for there to reach a sensible balance and have women (who represent roughly 50% of the population) represented by other women in parliament.
Your concern for the very rare man who loses out as a result of positive discrimination does not take into account the vast number of women who have been (legally in the past, and out of prejudice in more recent times) been passed over for positions that have gone to men. Current gender pay gaps are a testament to the fact that even now, there is discrimination in the workplace.
Why should it be a woman who can only work out of necessity (and who defines necessity?), and what sort of career can be done when her partner returns from his job? What if she has a female partner? Do they both need to be there in the evening?
Allowing women only jobs instead of careers is keeping them in a permanent state of dependence, which is not a good role model for children, surely? As has been mentioned, it also means that even in old age, women are poor, as unless you have 35 full years of NI contributions you will not get a full state pension, and working in the evenings only is unlikely to qualify you for a private one of any use.
