My point wasn't about having to reveal social media accounts you've not taken effort to hide, nor about the rights of non-citizens or citizens at boarder crossings. It was responding to a specific point made by another poster, about rights citizens have when choosing to speak (particularly on political issues).

Also, given that much of the revolutionary war propaganda and the federalist/anti-federalist papers were published under pseudonyms, Id argue anonymized political speech has been part of the American tradition since before there was a US government.
