I'm divided...on one hand, I get that this is really cool of her. A man who serves our country wants to hang with her, asked her on a total whim, and probably didn't expect this level of attention. On the other hand, these kind of things sort of creep me out.
I can't help but feel that she was mildly coerced into this. I mean, a number of the stories are reporting that Justin Timberlake pressured her to say yes, insisting that, "You need to do it for your country."
Hold up, let's clear one thing up right now. The sacrifices that our armed forces make to serve our country are enormous. They deserve a number of benefits in our society, but having an A list actress as your date to the Marine Ball is not one of them. This has nothing to do with Kunis, "doing it for her country" but rather, doing it for one dude who thought, "Hey I'll ask that hot chick and see what happens!" Service members don't get a free pass on the autonomy of the rest of us. That's not how it works.
Now, if Kunis has decided to do this because she thinks it will be fun, or she is touched by the request, or even if she feels it will be an amazing publicity stunt for her image and her career, then that's great. But it doesn't appear that she made the decision with free will, and that's troubling.
I guess all I can do is hold out hope that this is what she wants to do and the "pressuring" was all just a part of the stunt.
