nashashmi is gaslighting here by demonstrating two logical fallacies: both an appeal to authority ("Other nations also did this awful thing, so it must be OK") and putting forth a straw man argument ("I don't have any defense for what Pakistan did, so I'll accuse someone of bias").
I see no bias by hnews_account_1 here. I agree with hnews_account_1 in that the neighboring country they refer to (presumably India) would indeed have happily claimed Abdus Salam as one of their own and trumpeted his achievements; after all, Salam was educated in pre-partition India. In contrast, most Pakistanis today do not even know who Salam is because the Pakistan educational hierarchy deliberately ignores his achievements.
If anything, the notable bias (here, as shown by nashashmi, and in large, by the Pakistani establishment) is against the religious community that Salam belonged to. Since 1974, the Pakistani government (which polices who belongs to which religion, and forces you to declare your religion in government interactions) has imposed discrimination against this religious community by declaring them non-Muslim and preventing them from practicing their religion openly. Terror attacks against this community are common [3].
