You’re just equivicating.
It is WRONG to wear blends? You say God’s law says so. So, is it WRONG to do so?
Of course it's wrong. But we don't know in what context God considered it wrong. Scripture doesn't record WHY it was wrong or in what circumstances. Some have defined God to mean that it's ALWAYS wrong. As I said, God had a reason for avoiding wool and linen blended clothing. It would be wise to follow what God says even if it's only for a reason of physical comfort, commerce or any other theory that's been advanced.
