Christmas hasn't always been as commercialised as it is now.
When my father was growing up in the 1950s and 60s, his parents might take him into the city centre to see the lights at night, but his Christmas presents would typically be an orange (yes, really!), a few toys, plus practical stuff like clothes and shoes. Nobody really mentioned it at all until around mid-December. He could forget about wanting an £80 pair of trainers or whatever - there simply wasn't the money for that.
During my childhood in the 1980s and 90s, things had moved on a lot, but it was nowhere near as commercialised as it is now. One major change I've noticed is that shopping centres and department stores no longer put up Nativity scenes.
I can understand why, if you're not a Christian, you might not consider it relevant to you, personally, but the standard excuse that it might 'offend' people of other faiths doesn't cut it with me because: 1. Nobody from any other faith has EVER said to me that they find the Nativity scene offensive and 2. If you don't like it, just ignore it, there's no need to feel offended by it.
There were more presents when I was growing up in the 1980s and 90s than during my father's childhood, but the build-up wasn't as excessive or as commercially intense as it is now.
I DO recall there was a greater warmth to it, though, with things like brass bands playing Christmas carols in the high street, and one street near where we lived used to make a real effort to put up Christmas lights, something that fizzled out around the early 2000s.
Part of that warmth might just be nostalgia on my part, though. I came from a small family that was 'top heavy' on older people as I was growing up, and inevitably many have passed away as the years have gone by, which means that I have very few blood relatives to share Christmas with now.
