one of the most common things i hear, which is the flipside to "this is MY country, so you have to do everything MY way", is the old "but in THEIR countries we're not allowed to do XYZ, so why should THEY get to do ABC here".
the most offensive thing about the second statement: is the pretty strong implication that nz can never be the country of someone who has chosen to live here. if someone talking to me starts a sentence with "but in your country (countries)", i'm very likely to interrupt them with "listen f**ckface, your next sentence better be about nz, because that's the ONLY country i belong to". well no, i won't say exactly that, it'll probably be a politer variant.
but there's a deeper injustice going on here. just because some random country has some horrific sh*t happening to some of its citizens is not a reason to deny me rights in this country. it's likely i've never been in that country, i certainly don't have voting rights in that country and it might be a country that doesn't even have democracy. it's also likely that i totally disagree with what's happening in that country in the same way that you do. in fact, it's also very likely that a good number of the population of said country also object to the stuff happening there, hence arab spring for example.
so given all of that, why should i be denied any of the rights available to any other citizen in nz, when i have absolutely no connection to nor responsibility for stuff that's happening somewhere else in the world? and yet you hear it on talkback radio, in letters to the editor, on facebook and most other forums you could name.
there's yet another layer of nastiness involved in this kind statement. lets say i do come from one of those countries where some particular human rights abuse is happening. aside from the fact that this may be exactly why i've chosen to leave that country, there's a strong element of revenge involved here. in other words, what the speaker is effectively saying is "some people i identify with are being treated badly in your country of origin. therefore, i seek revenge by at least denying you some basic rights in this country". it's a tit-for-tat type sentiment that is not only unjust, but is plain ugly.
it's without any kind of sense or logic, and yet adult people are using this argument all the time. i don't get how they can't immediately see the sheer stupidity of it.
