Modern-day school system, democracy etc. are not free of faults/evils. At best (and at conceptual level), these are mubah (if free of anything un-Islamic). In practice, these are riddled with problems and un-Islamic features. There are traditional, alternative Islamic nizams (institutions/processes) which are superior to modern schooling system, democracy etc. So Mufti Chishti is not completely wrong in railing against these, even if he sounds anti-modern and "out of touch". Unless he does unqualified (mutlaq) takfir of proponents of schools, democracy etc. (so far there's no evidence for the same), he can't be labelled extreme. As far as his criticism of DI is concerned, he probably has few valid points; but it is unfair on his part to disparage it completely, without appreciating its positive contribution/impact. He seems to have softened his view of late (and he even quoted DI's Faizan-e-Amir Muawiya booklet in his recent lecture). He is answerable for his extreme views on DI, but not on the above issues. As far as his language is concerned, he may sound brash, vituperative at times (against his favourite targets) but he is nowhere as bad as Irfan Shah. Again, he is answerable for his language if used for people against whom he should be withholding his tongue.
