US citizens may not want to travel internationally because they don't trust US customs and border agents upon their return.

About 20 years ago a customs agent asked me, "are you thanking the lord Jesus Christ that you have returned safely to America". You just tell them what they wanted to hear and you were fine. Now if I am not mistaken, they can demand you unlock your phone which might show you were at a Tesla Takedown rally, or purchased a movie ticket to No Other Land, or whatever else is deemed verboten. I am unclear how long a citizen can be detained/delayed by a customs agent without cause.

Reminds me of this guy who had TTP revoked next day after he posted how US is becoming similar to PRC: https://www.instagram.com/reel/DHwEjGazRKx

I thought why do you care, this is just a fast lane but your comment was enlightening... (I am sure based on other recent cases they would totally revoke his visa if he was not a citizen already)
