If the next time I visit the US I have my laptop confiscated, my luggage searched or have my entry denied, so be it. I'll know that's because the US no longer welcomes free speech and plan my future travels and career moves accordingly.
I'll add that, if that ever happens, it'll be a sad day for me. I still have faith a country founded on principles rather than ethnicity or geography means something. I'd like to keep that faith, if possible.
When I exercise my fifth amendment right to silence when I am questioned upon attempting to re-enter my home country, I get arrested and harassed and threatened for hours and hours.
The phones are all tapped, the cops rule everything, and all of the basic rights we were told we had are now exercised only at the mercy of the military rulers.
A few years ago I went back to the US to visit the crypto museum (incidentally, right across the street from NSA in Fort Meade). It was my first trip to the DC area and the first night I got in, I went over to the Jefferson memorial. A sign on the pathway approaching the dome warns visitors that due to federal law, firearms are prohibited on the grounds.
Jefferson would be proud, I'm sure.
[note to non-US citizens: It's basic right #2 in the USA that people can own and carry firearms.]
