That's an interesting point. If you look at the law around sexual assault, the notion of consent is extremely important. That's a legal construct. There's a whole legal test that goes into determining whether informed consent was given.
I think everyone should be on guard within our legal system and our immigration system to ensure that, if there is a situation where parents have given consent, they are doing so in a very enlightened and educated way; everyone is aware of their rights; and this isn't a situation of coercion.
I'm not really sure what that would look like, but I think it is important to map out what informed consent would actually look like under these circumstances.
