Airyn stop spreading lies, studies result depend on whoever conduct them. I'm not saying that single parents are necessary bad, but having both male and female parent is much better - therefore that's what should be promoted and not same sex marriage. In term of slaves, since when do we (Christians) want to have slaves? To be honest if you are apologetic, you are already a slave to Islam. Continue to fallow everything promoted in media, I'm sure it will work out well for you.
