If Calvinism is true is God a racist?

Hebrews 3:
Warning Against Unbelief
7So, as the Holy Spirit says:
"Today, if you hear his voice,
8do not harden your hearts
as you did in the rebellion,
during the time of testing in the desert,
9where your fathers tested and tried me
and for forty years saw what I did.
10That is why I was angry with that generation,
and I said, 'Their hearts are always going astray,
and they have not known my ways.'
11So I declared on oath in my anger,
'They shall never enter my rest.' "[ Psalm 95:7-11]

12See to it, brothers, that none of you has a sinful, unbelieving heart that turns away from the living God. 13But encourage one another daily, as long as it is called Today, so that none of you may be hardened by sin's deceitfulness. 14We have come to share in Christ if we hold firmly till the end the confidence we had at first. 15As has just been said:
"Today, if you hear his voice,
do not harden your hearts
as you did in the rebellion."[Psalm 95:7,8]

16Who were they who heard and rebelled? Were they not all those Moses led out of Egypt? 17And with whom was he angry for forty years? Was it not with those who sinned, whose bodies fell in the desert? 18And to whom did God swear that they would never enter his rest if not to those who disobeyed[ Or disbelieved]? 19So we see that they were not able to enter, because of their unbelief.

 

God is all powerful you have no argument with me there. It's true He may not need to but He does. Convincing us of the gospel and convicting us of our sins is His method to bring us to our knees.
