I really don't get it. What's the point of caring and / or making a fuss over politics when you can't change anything on a large scale?
Tell it to George Washington, Thomas Jefferson, Benjamin Franklin, John Adams, Patrick Henry, etc, etc, etc.
"Why bother to oppose the King of England? It'll never do any good!!"
Have you never in your life done the right thing simply because "it's the right thing to do"(TM)? Or are your morals so shallow and weak that you only do right when there's a guaranteed payoff?
Your government has killed half a million people (or so), almost all of them completely innocent of anything other than living in the wrong country at the wrong time. And they continue to do it as we speak. Every day people are getting machine-gunned down.
Doesn't that seem wrong to you? Doesn't it seem worth opposing, even if your opposition doesn't accomplish anything?
Since I have no faith or religion, I'm not concerned about my immortal soul or any of that bullshit. And yet I seem to care about my government killing other people for no reason. But you, who believe there's a big man in the sky watching every action you take, measuring you for eternal salvation or damnation... you don't seem to give a damn if your government claims your consent on the cold-blooded murder of hundreds of thousands of innocent people. And now on top of that, you won't raise your voice nor a finger against them because... why? You're afraid it might not cause anything to change??
The sheer, staggering hypocrisy of claiming you have some moral high ground because you sit in a pew for an hour once a week, but then standing by while evil men do evil in your name... and then refusing to even TRY and oppose it... it boggles my mind anew every time I see it.
