It's not that hard to understand if you try and put yourself in their shoes and don't assume they are "disgusting, stupid, and small-minded". You aren't any different than them in your judgement of other societies, you just happen to have a potential advantage in education. What is your excuse for such derision?
You act like these people are animals and you aren't ever going to reach them and you are going to exacerbate the same impact you are talking about. Do you have the same view of all poor people embedded in a national culture?
As I was born in a conservative background and I found my way out in a long journey in a totally different country, I agree that people with the conservative background regardless of any country have a tendency to see the education, tech, big cities or most of the new things as poisonous to their core values. So that, they are trying to hinder their children to have access to these just because they love them and care them. They just want their kids to be happy and stay in the family as themselves who were kept by their parents.
In my opinion, this is not a new thing. This has been going for a very long time throughout the history. I understand that the change is scary from the conservative point of view. This is why; I try to not to judge anyone. But, I just see it as a puny fight against the windmill in the long run.
