"The row comes at a time when there are growing concerns that British universities have become too politically correct and are stifling free speech" Politically Correct AND LIBERAL!!!
To reach future generations Satan and sin will seek whatever methods to reach the next generation so that they will accept moral corruption and depravity.
Schools colleges and universities are a way of reaching the society of the future. We have already seen how the abomination of sodomy is doing every thing it can to convince the children that good is evil - and evil is good (Isaiah 5:20)
The education system found in modern society whether in Britain, America or Europe is depraved and corrupt with a view of the educators to corrupt young minds and remove all signs of Biblical doctrine and morality.
2Cor 4:4 In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
