If you love your daughter you have very little choice. In islam she is a slave so that daughter you love, you keep her close where you have some say on her treatment (your clan or close family) otherwise if you care nothing for her you marry her outside the clan or family where you have no say on her treatment in a society that has taught their men women are from the devil and a lower life form that you can beat or betray on a whim.
Mulsim incest is a form of love believe it or not. Islam is a sick religion and only leads to evil even when you are trying your best to protect those you love.

Different take, same net result.
