Perhaps the worst analogy of all time? It's not culture that has people in England driving on the left, it's the law, I don't think there are any laws in Texas that say you have to beat your kids, although I'm willing to be proven wrong since it is Texas.Did you not read my post at all? That is what their culture practices. That's like saying,"Why do those English people drive on the wrong side of the road? It's the 21st century, don't they know their right from their left?"
Again, not saying its right or wrong, but you don't seem to understand: that's just what is done in that culture. People don't seem to be aware of that, so I'm just pointing it out.
