"they bring out their inner monkey behavior and start harassing natives"
This is the kind of thing that makes me think that legalizing murder is a good idea. People from anywhere being obnoxious anywhere makes me think that, but people that go to other places in the world and behave like fucking chimps infuriates me even more, and it happens a lot in Asia. I know that there are plenty of places in Asia where people really hate westerners because of the way that tourists behave. They are making it harder for anyone else to go anywhere, and they turned the entire world into the fucking zoo that it is, with their retarded behavior.

To a degree, people in your own society being obnoxious is your problem, and it's your job to put them in their place and beat the shit out of them until they either learn how to behave or go to hell. Doing it in another culture, though, where people shouldn't have to deal with them at all, is especially bad. Especially when it's almost expected that tourists behave like shit. They feel like they can go to other places and shit them up because they feel like it's not their problem and like they paid for the right to be as subhuman as they want. Disgusting fucking apes. Dump them in the ocean and let the sharks deal with them.
