Wrong. We are to defend the Gospel of Jesus. Jesus told us to go and preach the Gospel to all nations, and to be willing to suffer and die for His name.
No where does the Bible tell us to defend or fight for 'religious freedom'. It is a misapplication of our lives to fight for our 'rights'. Those who fight for their 'right' will crumble spiritually once their 'rights' are taken away. Jesus said, "Bless are you when you are persecuted for My Name's sake."
Ultimately that's true. The only true freedom that can be known in this life is that enjoyed by one saved by grace through faith.
I was looking more at the "against" clause of his statement, with which I think you would agree.
