Why don't Christians kill their children for cursing?

[Igel]

22. Grammar, in this case.

He points out the dilemma: "Honor your parents, and if kids curse their parents they should die" is what you get out of the quotes.

Nowhere does he say to kill kids who curse their parents. Instead, the argument goes another way: That in fact the Pharisees de facto curse their parents by declaring their possessions a gift to God. If it's a gift to God, well, it can't go to help their parents, who remain old and without necessary money or goods. That's equivalent, you'd have to assume, to cursing them.

Now, if you want to take snippets and individual verses out of content, it could mean all kinds of things. Best to try to figure out what the text was intended to say and understood to be saying. That way we at least read what it meant instead of what we can possibly get it to mean.
