Yes, any Christian who votes for a pro-gay politician is attacking Jesus Christ, because the Holy Bible clearly shows that Jesus Christ as God hates ALL gay people (Genesis, Romans, etc.).
It is against Core Values of Christianity to love gay people. The Holy Bible emphasizes that national laws must outlaw gay people.
The New Testament emphasizes excommunicating gay people and not allowing them into any church.
Any Christian who supports gay rights stands for God and God’s Values, which opposes gay people and gay practice.
God wants homosexuality to be extinguished from all countries by law and death penalty imposed on all gay people through court process.
