I understand cultural relativism (I'm a history major and currently studying ethnology, not saying that I "know" how the world works, but saying I'm not just pulling my ideas straight out of my ass), and I know that it is tradition in many countries of the world to still marry their children young.
However, the way Wallishpls posted made it sound as if he was wondering whether the child had asked for it herself. Of course a little 8 year old child isnt gonna go ahead and say "you know what, mom, dad, brothers, uncles, grandparents, I do not want to marry this old man", shes a fucking child who will do what her parents force her to do. The fact that its part of their custom I can "understand" (although I on a personal level think its beyond fucked), however marriages like these are often business settlements or ways for families to tie tribes together. Women (and children) are basically property without any rights. When they do object to something they are either beaten up, raped or killed.
from wikipedia:
"Roughly half of Yemeni girls are married before 18, some by the age eight,[54] even though Yemeni law set the minimum age for marriage at 15; but tribal customs have often flouted the law. According to HRW, in 1999 the minimum marriage age of fifteen for women was abolished; the onset of puberty, interpreted by conservatives to be at the age of nine, was set as a requirement for consummation of marriage.[55] In practice "Yemeni law allows girls of any age to wed, but it forbids sex with them until the indefinite time they’re 'suitable for sexual intercourse"
What I'm trying to say is that sure, its a custom thats been going on for years, but I highly doubt that this little girl h e r s e l f begged to be married to some adult man.
Every year you hear about girls who live over here, go to school and are living like other girls their age. Then, summer break comes up and they go back to "visit family" in their home country, only to be married off to someone over there, arranged marriages where they have no say whatsoever. Some even committ suicide before travelling because they know whats going to happen.
