Who am I standing up for?

I read this quote today:

“In Germany they first came for the Communists, and I didn't speak up because I wasn't a Communist. Then they came for the Jews, and I didn't speak up because I wasn't a Jew. Then they came for the trade unionists, and I didn't speak up because I wasn't a trade unionist. Then they came for the Catholics, and I didn't speak up because I was a Protestant. Then they came for me-and by that time no one was left to speak up.”    Reverend Martin Niemoller

I just got me thinking about who am I standing up for?  Who are you standing up for?  It seems to me that in our culture, we are intensely self-protective and looks first at our own situation.  Maybe we need to be looking around for people who need someone 'to stand up for them'.....
