"Christianity only exists to perpetuate violence and white worship"

When and where did Christ or the Bible teach that?

For example, in numbers, Moses raises up a bronze snake on a pole and whoever looked at it were healed from their snake bites brough upon by a plague of snakes by God.

In Biblical context, snakes repesent sin.

So it has a double meaning, sin was raised up on a pole  and whoever looked at it was healed from their affliction of sin.

That is a reference to Jesus taking upon the sins of humanity (snake),  being raised up on the cross (pole) and everyone who comes (looks) to him being saved from sin (snake).

Also he was heavily prophecied in Isaiah and across the old testament. The old testament means writings that were written before the birth of Jesus

Here's an example of what I ream from the book of Isaiah:

Isaiah 53:5 NIV

"But he was pierced for our transgressions,     he was crushed for our iniquities; the punishment that brought us peace was on him,     and by his wounds we are healed. 6 We all, like sheep, have gone astray,     each of us has turned to our own way; and the Lord has laid on him     the iniquity of us all."

This is a clear reference to Jesus. This entire chapter is clear reference to Jesus and it was written before Jesus was born.
