I don't see how you come to that conclusion respect for non-christians is incompatible with Christians but whatever.So you agree that respect for non-Christians is incompatible with Christianity as you see it, but you aren't trying to persuade anyone else?
I don't believe that there's any prophecy in the Bible that spells out standards for celebration of Christmas or that failing to meet these standards indicates a "falling away from the faith."
You would have a much stronger case that, for instance, Christian stances against same-sex marriage and Christian boycotts of "woke" consumer brands indicate a "falling away"; at least that has a scriptural basis (1 Timothy 4:1-4).
Falling away is falling away from acknowledgment acknowledgment acknowledgment of Christ in any form.
Enough said I will not reply to you again bye.
