ok, but nobody was arguing that they are data points?

The parent was literally saying that he wanted to convey a different story to the ones commonly heard, in order to give a more balanced picture. Nowhere does that suggest anything about data points, just people sharing stories with different view points.

It's good to have a reminder that "anecdata" != real data every now and then, but in cases where you have a poster clearly acknowledging all that, bringing this up seems like little more than an out of place trope.
