Using the term "those Christians" is evidential of the successful demeaning of Christians secularists have tried so hard to effect. It shows secularists have no fear in looking down their noses at believers. Secularists consider Christians to be second-class citizens.
A culture devoid of Christian values is a dangerous wasteland of school killings, disturbed one-parent kids, crime waves, schools in a cultural vacuum teaching the destructive NEA--PP'hood agenda, sexual license, teen pregnancies, abandoned babies, abortion on demand including infanticide, and the homosexual takeover.
Those who disadain Christans must be proud of these "accomplishments."
I've always thought of secular as meaning non-religious in nature. Keeping Christian philosophy completely out of every public service....from secular counseling to secular schools.
I've never heard of a secularist (who I thought was a humanist) being labeled as a Christian.
I feel like I'm totally missing your points.
I have some errands etc..I'll check back in later..
