I seem to be more disturbed by this than others here. I have a few social media accounts & have nothing to hide. Mercifully I don't need a US visa, but if I did need one, I would not provide that information. We have to draw the line on privacy. If it means getting denied a visa, so be it. I would not undertake any discretionary travel to a country that asks this kind of information. What's next? My DNA?
I get that this has to do with protecting the homeland against "radical terrorists". No doubt there are many lunatics who want to do us harm, but part of the solution is to engage in de-escalation, i.e., revisit our foreign policy, which contributes significantly to the anger targeted at us.
