Still hardened. You said pharoah started it. That was a false statement, now instead of acknowledging it, you justify it. ScareyYou just ignored what was written
Those verses do not show God arbitrarily hardens men
In its context it refer to stubborn Israelites
of whom it is stated
Romans 10:21 (KJV 1900)
21 But to Israel he saith, All day long I have stretched forth my hands unto a disobedient and gainsaying people.
And Paul objector is a hardened Jew who argues why does God judge if if the Jew was fulfilling Gods plan by his stubbornness
You need to read the passage in context and not impose a Calvinist vs non Calvinist view upon it
