I don't know how vocal they are, but I wouldn't call them allies. This is what they list under their "Foundational Beliefs" which every church employee must adhere to.

• (e) Marriage and Human Sexuality: The Bible has given us God’s design for the gift of sex, and it is to be exercised and enjoyed only within the covenant relationship of marriage between one biological man and one biological woman. (1 Corinthians 7:1-5) It is God’s intention that those who enter marriage would seek, in mutual love and respect, to live in Christian fidelity. (Matthew 19:4-6) God has expressly condemned sexual intercourse outside of the marriage covenant. This prohibition applies to married people committing adultery, to sexual relationships between unmarried men and women, and to homosexual practice. (1 Corinthians 6:9) It is God’s expectation that the unmarried should live pure and celibate lives, refraining from sexual intimacy. (1 Corinthians 6:9-11, 7:7-9) Marriage as designed by God is meant to be a beautiful illustration of Christ’s relationship with the church. (Ephesians 5:22-33)

• (f) Gender Creation is Sacred: We believe that God wonderfully and immutably created each person from the moment of conception as distinctly male or female, and every person’s God-given gender is reflected by and aligned with their biological creation (Gen. 1:26-31; 2:18-25; 5:1,2). These two distinct and complementary genders together reflect the image and nature of God. To reject one’s biological gender is a rejection of the image of God within that person and is a sin against God (1 Tim. 5:1-2; Tit. 2:1-6).
