Sometimes, some things are so stupid that I don’t think they really warrant a serious reply.  Case-in-point:

Then I remember the horrid truth.  Most people have so little discernment that stuff like this would actually convince them that the critics of religion have made some kind of point.

Does that crucifix qualify as making a god out of cast metal?

In one sense, yes.  Jesus is God, and the maker of the crucifix has manufactured an image of Jesus out of cast metal.  Therefore, he has sinned.  But does that feel right to you?

The passage forbids us from making a god out of cast metal.  The real Jesus, of course, is cut from the same cloth as the Father and as the Spirit.  He’s not made of cast metal, but this crucifix is a symbol designed to remind us of the Savior.

So, what this passage is actually forbidding, for example, would be me designing an elaborate Staunton-style chess king out of brass with some custom engraving and decorations.  Then naming it George.  Then worshiping George as an all-powerful God of Chess, who has endowed me with both the interest and the acumen to play the game of kings.

Get it?

This passage is forbidding inventing a god out of workable materials.  God isn’t a being you manufacture from earthly things, he is one that you seek through heavenly things.  God is to be sought, not invented.
