The cultural and ideological difference is more. People from south have more awareness and honesty. The proof comes from the way they maintain their states.
Karunanidhi built a historical assembly building with German technology in just 450 crores. In the north one Adarsh building created a scam worth 2700 crores. Hindu-Muslim unity is more in the south.
In the north, people die and kill others in the name of God. That is why South politicians demand state autonomy like Kashmir.
In the same way as muslim majority ptan and bdesh got separated. But you hv raised a serious question by pointing out SSUDAN. But NIndia & SIndia have one thing common, HINDUISM, because of which we are still one.
But your agent Congres and missionaries are trying their best to create SS and ET in India. We seriously need to keep Christo popln in check if we want to survive. Christos are far more dangerous to India than Mussies.
Mussies at least participate in some Indian festivals but Christos,you'll find none. They are loyal to rome and vatican. In this decade our challenge is to keep a vigilant eye on thes Christos.
And i've often observed on tv that christos dislike to speak in Hindi. I was watching one tv program. There were 3 participants in that 2 Hindu girls and 1 Christo boy.
While it is believed that girls like to speak in English but on the show that christo spoke only his language English. The girls were occasionaly speaking in Eng. So the point is observe thes people.
How much they hate anything from India but cant show it openly and that will one day result in SS. See how quick the Christo country USA is to recognise SS. This same country was opposed to separate homeland for Tamils in SL because this would have resulted in a Hindu majority nation.
I think after Muslims and Chinese these Americans want Hindus to turn up against America and this will create new axis of evil USA, Islam-China-Hinduism.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
