if you're leaving the us this is like asking for animal products made without animal exploitation. go to the fl keys if it actully means that much to you. or deal with the reality that the American empire has dominated the global south and has basically broken whole countries so that rich Americans can do slavery roleplay. you can go and not engage in the more obscene elements but if you will never not be complicit, you can't avoid these unpleasant truths you have to acknowledge them. and as someone who has family in one of these beautiful island paradises where most of my relatives are living in conditions Americans could never imagine.. its whatever if you go, I dont think you're a bad person right? the same way I don't personally think people who eat animal products are bad people (pretty sure you disagree there tho lol) but you cannot deny the reality that they are engaging in unnecessary exploitation.
but yeah you have tropical beaches at home (they suck but that's what happens when you destroy the environment). i saw you considering Vietnam, that seems extreme just to go to a beach, dont get me wrong i wanna visit one day but that's so much money JUST to go to a beach.
