4. Jibran Nasir Child protection activist
5. Mother of Sonia Kumari
6. Hindu activist unnamed for fear of repercussions
7. Mullah Kaifat Ullah, one of a half-dozen clerics who also performs marriages in the complex (above a wholesale rice market in downtown Karachi)
8. Arzoo’s mother, Rita Raja
9. Nasir, the activist
10. the pastor's family (of Neha) at a Christian church in Karachi
There are possibly others I've missed, but of course the names of activists and witnesses are withheld in a country where there can be repercussions of blasphemy for the things they have said.
As for most of the rest of your post it seems to be whataboutery.
Personally I applaud
@Vinayaka for sharing this story, as it is needed to put pressure on those responsible for such crimes in Pakistan.
