Don't be intentionally (I hope) obtuse. I'm not saying everyone should get a visa, I'm saying universal human rights should be repected by all governments that supposedly recognized them. Allow or deny the visa, but respect the applicant's dignity.

Privacy is one of those analienable universal human rights recognized by the UN, and demanding to see the social networks of other is infringing it, regardless of citizenship or immigration status. It's not only a faceless government employee(s) probing and ogling your social life, social networks allow private messaging, which becomes non-private after these unreasonable demands.

Don't normalize the erosion of human rights.
