Interesting reaction, but what does it mean?

I was just thinking about this whole Christmas thing, and the many different attitudes towards it i'm seeing expressed about the place, and i'm wondering if the pattern behind it is as simple as it looks - that a major factor really is the 'spirit of Christmas past'.

I've noticed that a few people who seem the most excited and hyped about Christmas also seem to have had a strong Christmas tradition in their family and wonderful memories from their childhood that they want to continue and share with others. Is that true in general or just for some?

Those of us (like me) that don't really care much about it, did you (like me) come from a family that didn't really go into it that much and so don't really have a tradition to care about either way?

And those out there that totally, utterly detest it - what's the deal? Does it hold bad memories or other connotations? Or are there specific things about it that offend you?

Give me the lowdown people, because enquiring minds have nothing better to do..

(Well, i do have things to do, but 'better' is subjective).
