No, that sounds about right. I don't blame others for caring, or think they shouldn't care. In fact, I'm glad they do. But I don't.
> You should care about things that don't directly impact your life -- partly because you can make a difference in these things, sometimes, if you get involved.
Fixing the military industrial complex or some other country's fucked up government isn't really on my TODO list. For better or worse, it's not how I want to spend my life.
Aligning your circle of influence and circle of concern is the key to productivity and happiness.
Moral fashion is all the rage, but unless you are going to engage in the political process (properly, not just retweeting hashtags or sticking bumper stickers) then you're better off not bothering with it. People spend far too much energy on fashionable 'global' causes when there are a pile of local causes that need their help.
I am sure this is not quite how you mean it, but to me this comes across as saying "if it doesn't affect my life, or my friends, then who cares." You should care about things that don't directly impact your life -- partly because you can make a difference in these things, sometimes, if you get involved.
Time to get out of the shire and see the world, bilbo.
