No, your attitude is completely selfish. That's okay. Some people truly believe this brings them happiness, or they just are not able to have an all-compassing vision that goes further than their own needs. To be frank, I could care less about you, but since you ask, here's the thing:
If you were an ermit, a hobo, some homeless person on the street, I'd say sure, worry about your own problems, you have enough as it is! Besides, it's not like in those situations, you would elect some assholes and then pay tax money to pay the salary of politicians who make it their missions to fuck up and destabilize so many other countries! It's not like, if you were homeless, you would pay tax money to invest in wars and weapons! It's not like, if you were an ermit, you'd buy tons of products that would destroy the planet (either because of their lack of ethics or because of their lack of sustainibility).
If you live within society, you impact society. Because of the way society is running now, by being your kind of neutral, you're just lending weight to the snowball of Bad Things Happening.
You can act like the people who just talk about things on forums just "pretend to care" but don't have much impact. I'd probably agree. I don't really like the fact that I don't have the impact I want. I tell myself, oh, but at least I'm not from the States, so my tax money does not go to useless wars or attempts to destabilize poor country just to my politicians can then abuse the situation. But I'm from Canada and even if our country is (or was) better (yay, people of my country don't have to worry about healthcare!), we have the Harper business, and there's only so much I can do even for my own region.
I can protest in the street, I can write articles and essays, I can take part in a strike, I can have as many conversations as possible to see if people could be open-minded and care enough to pay attention to what the people who care about the future of the country and of other countries are screaming in the street and explaining more quietly, but with the force of more details, on paper and online.
Because it needs to be both -- the people who go and protest and who organize projects can DO stuff all they want, the majority of the people stays silent and uninterested in the fate of the world, and then the politicians point at those people who will never budge (unless it's something that they care about very personally), and they use those quiet and uninvolved people to say, "Yeah, so you have a minority of people who do things, and then you have another group of people who send us letters and petitions and talk bad about our laws, but look at this mass of people there, they just want the subject to go away so they can focus on entertaining themselves."
The silent majority.
People like you.
People who just don't care, and who are proud of it, and who do have a stupid weight and I wish you didn't.
End of the story:
Everybody has an impact -- if you don't want to orientate the direction of yours yourself, someone else will be happy to do it for you.
