Think the situation out.

Had the runner not interferred, would the defense been able to throw to third for the tag out then on to first for the force out? Probably not. So why then would you want to give the defense two outs here?

Second, lets say there were no outs here. So the defense just went from a 0 out, runner on second situation to a 1 out, runner on first situation. How was the defense injured on this play to justify the two out call?

You don't have to be a book worm on the rules if you can just think out the situations and find the injury and then who benefits or suffers.

You explain it like that to them, they will understand better. Although, that MAY depend on how much beer they have had up to that point.
