Hey Catholics for Choice:

Human life must be respected and protected absolutely from the moment of conception. From the first moment of his existence, a human being must be recognized as having the rights of a person - among which is the inviolable right of every innocent being to life.

-Catechism of the Catholic Church 2270 


To oppose Darwinian biology is not to announce yourself neutral or disinterested or even uninterested. It is to announce yourself against the discoveries of science, or so frightened of those who are that you can be swayed from answering honestly.
—  Adam Gopnik on the evolution catechism.
If someone is gay, who searches for the Lord and has goodwill, who am I to judge? The Catechism of the Catholic Church explains this very well. It says they should not be marginalized because of this (orientation) but that they must be integrated into society.

Pope Francis

CCC 2358 The number of men and women who have deep-seated homosexual tendencies is not negligible. This inclination, which is objectively disordered, constitutes for most of them a trial. They must be accepted with respect, compassion, and sensitivity. Every sign of unjust discrimination in their regard should be avoided. These persons are called to fulfill God’s will in their lives and, if they are Christians, to unite to the sacrifice of the Lord’s Cross the difficulties they may encounter from their condition.

If you do not love your enemies, you will not experience the sweetness of the Holy Spirit. It is the Lord Himself who teaches us to love our enemies, to feel and suffer with them as if they were our own children. The Holy Spirit is Love, and this love fills the souls of the holy citizens of Heaven … There are some who wish the pain and torment of eternal fire upon their enemies and upon the enemies of the Church. By thinking in this way, they do not know the love of God. Whoever possesses the love and humility of Christ weeps and prays for the whole world.
