Of course he’s allowed to express his opinion. That’s what free speech means. It also means that other people can call him out on it. I stand by my assertion that dropping out of high school is almost always a bad idea.
I think it is extremely unwise in our current culture for a 16-year-old girl with no marketable skills to get married and devote her life to taking care of children, before she’s even a legal adult herself. If she’s younger than 16, she won’t even be able to drive. She’ll be completely dependent on her husband, and she won’t be able to get a job elsewhere if she doesn’t have a high school diploma or GED. If her husband becomes the head of a multi-million-dollar company, she’ll be fine. But if anything happens- sickness, disability, or death of the husband- she won’t have many options at all. She’s stuck, with no way to provide for herself or her children.
Now, if a somewhat older woman wants to do the same- one who’s finished high school, one who’s been driving, one who has work experience, one who’s dated more than one person, or the same person for months, and really gotten to know them well- I say more power to her. But in our current culture, I don’t think it’s a good idea to encourage teens to close off most of their options. In our current culture, people ought to have basic life skills before they get married.
Once again, I’m not saying it can’t work, or that it didn’t work in the past. I’m saying that it is now generally unwise.
