Why so angry?

Tell me, is it possible to have a passionate commitment to ideals (political, feminist, religious) without being so angry?  I want to keep abreast of what’s up in my world, but somehow, I find many bloggers to be all-pissed-off-all-the-time.  It’s exhausting.

Then again, maybe that just means that I’m not a good (progressive, feminist, Christian, fill-in-the-blank).  You tell me.
