"But South Indian cinema does the same thing to itself!"
This could be attributed to Gentile Eurocentrism among the broader populace. In the north, however, I believe there is a Turanian element to this.
"therefore Indian anti-Turanism should never have been categorically anti-north in the first place."
But in the present-day context, as you have pointed out, the North is more Turanized than the South. So would you say this attitude is something that we could capitalize on?
