A judge might have a “right” to punish people for things they didn’t know were wrong, but this is a judge who created those people without giving them the capacity to know right from wrong in the first place and then punishing them for doing the wrong thing anyway.

And of course a Christian apologetics website is going to give the kindest possible interpretation to that passage.

I’d also note that it’s part of the Jewish half of the Bible, so maybe finding out what Christians think about what it means is the wrong way to go about convincing people of your point. Maybe consult a Rabbi’s interpretation instead.
