I agree with the sentiment but for me Christmas (and birthday's) aren't about duty. Rather they're what you make them. If Christmas is a time of reflection and appreciation for me, then it's an annual reminder to think about the people around me, and an opportunity to put that into some sort of action - be it a gift, or a card, or something else. There's nothing stopping it from being genuine.
Having said that, it's true that most people don't feel as though they can skip doing something on Christmas, that they do feel obliged to do something 'or else'. For me, I've found that it is 'more blessed to give than receive' and that if I'm honest with myself, I do need regular reminders to get my head out of the clouds, or my own rear end, and reflect more deeply on people and do something for them. So I welcome the opportunity to do so, and relish the opportunity to find some way to do something for them. I'll admit to being more stubborn or rebellious than a lot of people in terms of not caring about convention and being willing to ignore or reject it - so I don't care too much about the peer pressure. For me it's about doing what matters or what's good, and Christmas is a great opportunity for that.
I will say I only focus on close family/friends and I don't mind writing something or being creative in that way rather than buying and giving something.
I'm always adamant with people that they shouldn't follow the sheep and feel the pressure to buy things for anyone (let alone everyone) if they can't afford it or are getting into debt. There's no point to any of that - it's just keeping up with the Christmas 'Joneses', so to speak.
So yeah, if it means nothing, then why do anything? But maybe it can teach us/remind us about something meaningful?
