The one useful thing about your comment is that it gives us a way to measure the background radiation of mean-spiritedness online. Watsi is about as good as anything ever gets. The founders are as selfless as anyone I've known. And they are not merely unrealistic do-gooders. They know well what things are like in the field. If people wholly focused on doing good and very effective at it still manage to get attacked online, that's therefore the baseline for being attacked online.
