Suppose there is a set of ideas circulating that has a grain of truth but is being interpreted and applied by many in a bad way. Should you steelman the ideas, to acknowledge and draw out value in them? Or fight the ideas, to counter the bad influence they are having on others?
I also do variants on this when I think the ideas are mostly fine but I'm explaining them to a hostile audience (e.g. sometimes when explaining relevant feminist theory to men who don't want to hear about it)
