My experience of there being plenty of people online who will change their mind isn’t limited to only rationalist circles, though it is mostly limited to circles with people of above average intelligence. Perhaps if you are actually talking about the average Internet user, it’s justified to make the kind of assertion that you were making, but I wouldn’t expect most LWers to hang out in the kinds of online circles that are dominated by average Internet users.
