Never forget that while there is 'freedom' to become what one likes (eg homosexual) for non-Christians, Christians should not exhaust themselves opposing the world's agenda by any other means than our Lord demonstrated and directed.
We also have 'freedom' to use the civil liberties still available, to bring up our children in the nurture and admonition of the Lord, and to protect them from being trammeled by the impurities in the formal education system. It is up to us to be and to do for the Glory of God, cheerfully showing that there is a better way. This is what we do. This should not be a chore.
Not for a second am I suggesting it's not a huge challenge; but perhaps Christians will appreciate each other's efforts in these things, and find causes for unity rather than division around them - the very practical things of everyday life. It is here that we feel ourselves 'escaped from the corruption that is in the world through lust' (2 Peter 1); it is here that churchtime is indeed a sweet escape into the presence of God.
