Good news, since I reluctantly activated moderated comments, I've only had to delete one post. Bad news, that was a piece of spam for some financial scam, so the spam bots are finding their way past Blogspot's letter-code entry system.
It was unfortunate, but all too common, the way the comments threads had started as an intelligent discussion and degenerated into a peta-realm of insults and trolls. We've all seen this kind of thing far too often on the internet. Is there something about the medium? The anonymity is a factor, no doubt, and also the casual ease of posting which means a person can upload something in a bad mood they might later regret.
But remember, Buddhists, there is karma attached to speech. Speech is a power we have of inserting dhammas directly into another being's mind-stream. The internet if anything multiplies this power, and the karmic repurcussions.
One of the formulas for right speech is the four-fold one of what speech a Tathagata would utter. A Tathagata only speaks (a) that which is true, (b) beneficial, (c) meaningful and (d) either pleasant or if unpleasant, spoken at the right time. In the context of the internet, and of this blog, I take (d) as permission to disagree but with respect and care.
Another point, and one I've addressed before, is that I occassionally get criticized for raising political questions here. Although I may sometimes slip up, I try to do so with discretion and care. Buddhism, and Buddhist ethics, ought to practical and relevant to real-life. And it seems to me that there are two very important areas of concern, war and climate-change, that could urgently use the application of Buddhist ethics. If we can't apply those ethics to the momentous issues of the day, then they are only museum relics. So, I don't intend to stop.
