Nothing right wing about it.
Jesus called God, Daddy. Not Dad, Not Father, not God. Not once or a couple of times, but every time but one, the one mentioned here.
When Christ was on the cross, Daddy became God the Judge, and Christ became us. God turned His back on sin. The only time Christ had sin was when he was drenched in ours, on the cross. He endured being forsaken, so we will
never have to. Once our sin had been dealt with, the Judge was able to set that role aside (100% just) and concentrate on being our Daddy.(100% merciful)
The Daddy whose grace can't be out sinned. That is why we go to Him
through Christ. Because Christ changed places with us, now we can call Him Daddy too.
Hebrews 8:12 For I will be merciful to their iniquities, And their sins will I remember no more
