Christ's birthday

[Pope Alfred]

I can't assert my belief as fact. See above.

In effect, that's what you're doing. I can see from everything you've posted here that you hold both as if
equally valid and real. You're just wriggling on the hook about definitions.

I notice that Christians who go on about 'faith not needing proof' will damn soon change their tune if they think they've found a little bit of historical or scientific evidence.
