It's not. I take you are comparing to western countries. If you have a valid visa and behave even remotely normal to the border agents you will have no issues. Only in the USA some border agents have the attitude of "I'm gonna get you" or making you feel unwelcome for no reason. Hell, even in "authoritarian" countries like UAE or Quatar I never experience anything but pleasant interactions on the border.
Wikipedia seems to indicate I couldn't go to the UAE because I'm transgender https://en.wikipedia.org/wiki/LGBTQ_rights_by_country_or_ter...
Be strong.
This is the crux IMO: it should be an OR not an AND. Having to behave "remotely normal" where this is determined solely at the discretion of the TSA is impossible.
Just recently a woman from the UK was denied entry into Canada and because of that was denied entry back into the US and found herself in the same mess as the person in the article.
This happens all the time, you just don’t hear about it until the news decides to make a thing about it.
You are proving my point, she was again detained by USA for 3 weeks when it could have been resolved much better and faster.
