The fuck are you talking about defending forced marriage? Do you have reading comprehension issues? Is English not your first language? The law is they can get married at 16, and often below, WITH CONSENT FROM THEIR PARENTS. I am sorry this is not jiving with your idea that this is a US problem. Most countries in the world work like this. This is a problem with humanity.
What part of me saying this is a problem with the world, not just US, told you I was defending the practice? Seriously, is your reading comprehension poor, or do you struggle reading English? If it’s the latter then it is just a misunderstanding, if it if the former, well, there are many online resources to help with this.
