Rubbish? Make logical arguments. It's not about getting everyone to collage, but millions of women who wanted to go to a college but couldn't do so because of pressure back home. That is when you complete senior schools, you will be 17-18 and are soon getting married. Not to mention those getting married before 18 which is quite high.
21 is the right age, in fact, in many countries, it's the legal age for women to marry. Now, if they become call center operatives great, I mean earning 15-20 k a month is not bad for a women and I'd have no problem with a lady getting a call center job than sit at home and cook. Maybe that's what you think women should do.
