Good thanks.
We can dance around these words and terms forever.
Takfiri is not a new group. The whole terrorist soup in Pak these days is run by Saudi/gulf charities so obviously the funds go to a particular sect. And they reject secular vision of Pakistan.
Similarly Iranians have in the past funded Shia militant organizations. Similarly Iranian brand of Islam rejects secular vision of Pakistan.
Why because religious ideology imported from Iran or Saudi will never fit in Pakistan’s multi-ethnic and multi-religious environment.
If we want to ignore all that, and make up some new term like Takfiri, we’d remain stuck in this sectarian mud .
