Ooo there’s a lot to unpack here.
Within the religion, responsibilities within the congregation are different between the two sexes. Men can be elders or ministerial servants which are two things that women can’t be. Elders and ministerial servants can give talks on the stage whereas women can’t.
Within the organisation, it’s discouraged to pursue further education (uni) as studies will take up more of your time and leave you with less time to be out on the ministry. Saying that though, there is no ‘consequence’ for going to uni. Most Witness’ that I know, have a degree!
The reason why I’m saying all of that is because the girls you know may have thought, ‘well hold on a minute. Why would I get baptised and live a minimal life when I can further my education and possibly become a director/CEO etc.’ Whereas some men are probably happy to work towards becoming an elder as they’ll have more responsibilities.
This is just my guess though! I know more men that haven’t got baptised than women. I know a lot of women that haven’t got baptised, left and came back and ended up getting baptised. I don’t think there’s a clear divide (in terms of what people choose to do with their life and their place in the religion) between boys and girls/men and women. It probably just depends on the people we know!
I personally don’t think anyone is being indoctrinated. Children may be raised as JW’s (like me) but there’s no obligation to get baptised if you don’t want too. No one forces you to believe or accept these things, as you’re encouraged to think for yourself as an individual. You can’t get baptised as a baby/small child unlike in may other religions. I think the youngest you can get baptised is 12/13 however if may have changed (I doubt it)
