Why Christians have created such difficult languages?

I think you have an issue with the West as a whole, friend. English is not to blame for its complexity. Think of it as itself a multicultural product of marrying German, Latin, some French, and a good deal of onomatopoeia. As for the lack of rights for illegitimate and/or low income children, it's clear that you've not researched policies on Child Support, WIC, and Department of Human Services in the U.S. Sure, they are far from perfect, but the effort is there. As for the countries of the Middle East, they incorporate their religion into political practice. The separation of Church and State must remain in effect here to maintain national peace, something that many countries in the Middle East have yet to experience for very long in my lifetime.
