So you think declining to state isn’t going hold up your entry? You have more faith in the DHS than I have. What if someone is like me and they don’t have a social media account? Will they hold this against them when they decide to expand the program and make it mandatory for everyone (because we all know they will expand it)? Finally, what keeps a visitor from setting up a dummy account just for this reason? Does this make us safer?
Honestly, I think that the government just wants access to your contacts so they can snoop. Just like the LinkedIn, Google+, and Facebook requests I receive because someone allowed these three companies unfettered access to their contacts.
