Okay I just want to point out to those of you who are assuming those making the joke are white, privileged, entitled, supremacists, that a lot of the people making these jokes are those who have zero means of actually doing it. That's why it's a joke. You don't have to have money, power, and privilege to make jokes. I'm sure there are some people who are serious and it isn't much of a joke, but the majority of the people saying this, yes, they are joking, no one should be taking it seriously or guilting them for it.
And to those of you who think they're just not doing their research and being presumptuous for claiming they're going to make the move, I'm going to point out again that the majority if the people making the joke have zero means of actually doing it, NOR would they even CLAIM that they could. They're not being naive. The first person I even saw make this joke was my best friend, and she's the last person in the world who would make a big leap like that without knowing she could do it in the first place. And before anyone gives more of that "but even joking makes minorities feel bad" crap, she IS a minority. And I'm not about to sit there and say "wow, you shouldn't be joking about that" when A) I KNOW she's just trying to help herself feel better and B) I'm white, and if I EVER even TRIED acting like I knew better than her on minority issues, she'd slay me (and I'd take it too, because I'd totally deserve it).
Sorry if this sounds heated at all. I'm just very against making people feel bad for trying to help themselves feel better about all this, because it's already crazy enough as it is, we don't need to turn against each other just because some people need to make jokes and blow off steam. There are more than enough people who fully plan on staying in the country even before this argument started up, so no one's being abandoned. Just because some people are serious about it and will try moving, doesn't mean they all are.
If you are a minority, and me saying this makes you feel bad, I do apologize, I'm just seeing an awful lot of people who aren't minorities over twitter and tumblr claiming these jokes shouldn't be made, when the majority of the folks I saw actually making the joke are minorities. That just feels bad, man.
