My general approach is that ‘it’s the internet’ and that what someone writes reflects more on their own character than on anyone else. I’ve been a denizen of the internet for more than 20 years, and I probably have too pollyannaish a view of what kind of free speech community it was supposed to become that derives from a mindset formed in the early 1990s.
More importantly though I question my ability to be particularly Solomonic in my approach to moderating comments. It’s too easy to let distaste for a commenter’s truly offensive posts become a slippery slope into dislike for someone who thinks I’m deeply and morally wrong on some issue.
