To the first one I would say that Jesus told us to go and “baptize all nations in the name of the Father and of the Son and of the Holy Spirit”. He also told us to “instruct and ignorant” and “admonish the sinner.”
Leaving people in their ignorance is not God’s will. The world will change when hearts change. Giving them the truth will enable them to grow in holiness.
The second one sounds like a lot of intellectual clap-trap that tries to make the Church look wrong. Anyone with a way with words and some half-truths can do that.
