Now you've done it. I've taken the bait.
First, I'm not sure what you mean by the statement, "whomever takes such a stance ceases to be Christian, as defined by the Bible." My understanding (perhaps different from yours) is that a Christian believes that Christ is the Son of God, sent to redeem mankind from the sin of Adam and Eve.
Once you've acknowledged Christ as the Savior, you go out and tell others.
My take on the adapting their pagan traditions to Christian beliefs philosophy is that it helped explain Christian beliefs in a way that was easy to understand. For example, the celebration of Spring Solstice and Easter commemorates rebirth both of the earth and of mankind, since man was reborn through Christ's Sacrifice. Just as the earth comes to life every spring, man comes to life through Christ.
The Christian tradition slowly but surely replaces the pagan tradition, and even when a society becomes secular (as ours has), the tradition of an Easter celebration makes the Christian aspect of the day hard to hide (even for the most determined Atheist).
So we have a pagan holiday that was co-opted by the Christians, and the modern-day secularists cannot overcome the religious significance because the holiday has come to represent the Sacrifice of Christ.
Who says God doesn't have a sense of humor?
Ahhh, but the Christian does more than simply "believe" - he embraces the relationship, following God's Commandments and His Word. Hiw Word is not open to personal interpretation and God's word does not change. So, to take action that goes against the word of God is Christian, but apostate. The Bible defines exactly what a Chtistian is.

Problem is, God doesn't compromise His principles. To teach otherwise is apostate.
