"For example: After an incident involving an American in Brazil [1], all Americans were out of a sudden required by the Brazilian authorities to get pictures taken at the Brazilian customs. The situation got so ridiculous, that at some point the airports ended up with 3 lines: "Brazilian Citizens", "Foreigners", and "Americans". In other words, Americans were singled-out from the rest of the world. Would the OP describe that as a "pleasant experience"???"
Why should Brazil treat US citizens any different, than the US treats Brazilian citizens? If the US harasses Brazilian citizens with such procedures, it is IMO perfectly OK if Brazil does the same to US citizens.
Why did this get upvoted? You're dodging the point of the comment. You're logic seems to be:
Person1: Bad things are happening in the US
Person2: Well, bad things are happening in Brazil too.
Person3: But it's only fair for the Brazilians to do bad things
because the US is already doing bad things.
The original article is griping about how bad things are travelling to the US, and how it's not that bad travelling anywhere else in the world. Someone countered with some examples of bad experiences travelling to Brazil, and then you responded saying that it's only fair for them to go tit-for-tat (which really has nothing to do with the original discussion).
Someone commented that the situation in the US is actually not that bad, and that it's worse in Brazil: "Oh, c'mon, this sounds very over-the-top. My experience is that TSA and USCIS (formerly INS) are very professional and follow a strict protocol. The protocol may be unfair or not, but that's the protocol, not the professional's fault. In places like Brazil your entire trip is at the hands of chance: Most times you get a nice officer, but sometimes not."
But that's not true. Travelling to Brazil is rather unproblematic for citizens of most countries. Only citizens of countries that harass Brazilian citizens are harassed equally.
So I agree that related to the original article my comment was off-topic. But it's very on-topic in regard to the off-topic parent posting (because from a non-US citizen's perspective there aren't any problems when traveling to Brazil, but plenty of problems when traveling to the US).
Why should Brazil treat US citizens any different, than the US treats Brazilian citizens? If the US harasses Brazilian citizens with such procedures, it is IMO perfectly OK if Brazil does the same to US citizens.
