I don't agree with most choices people make, but it's more of a "I wouldn't do that" kind of thing. I very much think that you should do you, as long as you aren't hurting anyone.
But something that does hurt people is others calling them names, or telling them that their choices are wrong or disgusting, simply because they wouldn't have made it.
If you want to have a family young, fine, go for it. There is options available if it's unplanned and not what you want.
If you want to remain child free your entire life, fine, go for it.
If you want to sleep with another adult who also wants to sleep with you, you're both free to do so and consent to whatever, fine, go for it.
If you want to have a relationship with someone decades older than you and you're both entering into it with consent, fine, go for it.
You want to have a career, fine, go for it. SAHM, fine, go for it. Both? Fine, go for it.
Want to use your choices to beat someone else down? Not fine, back off.
