It is NOT OK according to God's Word.
God deemed homosexualty as a sin, and an abomination.
Apostle Paul condemned homosexuality also per New Testament doctrine, and even said those who practice such shall not enter into the Kingdom of God.
In Apostle Paul's time, some of the early Church's members had practiced that lifestyle, but came to Christ and left that lifestyle. Apostle Paul covered that point in his Epistles also. Thus there are plenty of Bible examples that reveal homosexualty is an un-Godly practice.
How then, can one who 'claims' to be a Christian, justify ANY adult pushing homosexual material upon little children?
I'll be more blunt about such evil as reading that sin to innocent children. Homosexuality cannot produce pregnancy, because it is act against God's natural creation. For that reason, the gay community must 'make' future homosexuals through training. And that is exactly what the old pagans that were without God did, like those of Sodom and Gomorrah. Their destruction by God's fire per Genesis 18-19 was not a myth. It actually happened.
So anyone... even saying that it is OK to train little children in that lifestyle, is NOT a true Christian according to God's Word.
