That doesn't sound like an activist. That sounds like "sucker doing other people's work for free", which doesn't sound like an effective plan for bringing about positive change -- those people tend to "weed themselves out" over the long run.
I'm not saying you shouldn't do things to make the world a better place, like: not litter, drive courteously, etc. (Although you should be careful about which things actually accomplish a net good.) "Be the change you want in the world" (attr. Ghandi) is a good motto to keep. I'm just saying that you shouldn't expect major problems to get solved by Someone Else at no cost to you, nor complain about someone pointing out the dirty river instead of immediately cleaning it up.
Does this work better for you?:
"The rationalist is not the man who complains about biases. The rationalist is the man who works to understand his biases."

A monthly thread for posting rationality-related quotes you've seen recently (or had stored in your quotesfile for ages).
ETA: It would seem that rationality quotes are no longer desired. After several days this thread stands voted into the negatives. Wolud whoever chose to to downvote this below 0 would care to express their disapproval of the regular quotes tradition more explicitly? Or perhaps they may like to browse around for some alternative posts that they could downvote instead of this one? Or, since we're in the business of quotation, they could "come on if they think they're hard enough!"
