Yes this is a very evil world. But remember this...
Proverbs 22:6
Train up a child in the way he should go, and when he is old he will not depart from it.
You did not state if you daughter is considering the homosexual lifestyle. So I'm going to assume she hasn't. Here is the thing... in this life we will run into all types of influences. Whether in High School or on her first 'real' job. There will be people all around us who can, if we allow them to, affect our walk with God. You are concerned, but remember Proverbs 22:6. Your job is to teach your child and bring them up in the Lord and God will handle the rest. You can't protect your child for ever. Who knows, maybe her having a good example and bible teaching at home will prepare her to counsel others at school or in life in general. Pray for your daughter, teach your daughter and prophecy over your daughter the plans God has for each of us which are stated in Jeremiah 29:11 For I know the thoughts that I think toward you, says the Lord, thoughts of peace and not of evil, to give you a future and a hope.
The teaching and example of a Christian she has at home will stay with her always. Be a good example and teach her God's word. Plant the seed and the harvest will come.
God Bless!
