patience is difficult
I'm with you Rob ... it can be exhausting to speak the truth in the face of inaction. I deal with this all the time in my own life -- particularly as regards my relationship (or lack thereof) with my partner's fundamentalist family. It is difficult extending a hand of friendship when none is extended back your way -- it is difficult speaking the truth to people who are too afraid to recognize it. As you point out, it's also difficult to watch well-meaning people of faith accommodate injustice by doing nothing. (I should know -- I'm Lutheran!)
In any case, I believe -- for me -- God calls me to patience in such situations ... but also to an absolutely steadfast commitment to speak my truth. If I am able to speak the truth in love in all of these situations, then I've done all that I can. This may or may not mean that I am polite, this may or may not mean that I make others feel comfortable, this may or may not mean that I speak at no cost to myself ...
Anyway ... just some thoughts. My prayers are with you ...
