"My faith is a very private thing." Sorry! - Not allowed!
Matthew 28:19-20 states what has come to be called the “Great Commission”: "Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age."
Jesus gave this command to the Apostles shortly before He ascended into Heaven.
Keeping this 'privacy' sacrosanct, means that Christians are not loving their neighbours; all those people condemned to a lost eternity.
The essential difference between evangelical Christianity and liberal christianity is that the former cares about those who do not know how to access salvation; the latter prefer to put their trust in man and categorically refuse to worry because they falsely believe that "God will not condemn anybody."
Only one problem - The Scriptures are about God the Son DYING to save any of mankind who are tuly repentant and commit to Him. It is made abundantly clear that failing to take this route leads to hell.
Liberal christians may 'care' but not where it really matters!
