Christmas being sooooo tacky and shit and over commercialised doncha know.
He and his DC have their Christmas on solstice instead. And ohhhhh boy don't we all know about it. If you say "merry christmas" to his DC (8, 10, and 11) they tell you "we don't do shitmas" (yep, in those words). BIL loves to lecture us on how shit and commercial christmas is and how he thinks solstice is so much more important blah blah blah.
I'm not averse to solstice celebration tbh and we usually get out for a sunrise walk (didn't bother this year as was so grey and gloomy at 7am) and then have a little fire in the evening to mark the day. The sun returning feels special to me and I love to think of the days getting longer again.
But BIL has basically just shifted all the stuff he claims to despise about Christmas to solstice instead. His DC get piles of gifts and spend months talking about what they want and asking for specific ££ things "for solstice". They also kick off if they don't get exactly what they asked for or if they think one of their siblings has more then them, or for something they've decided they wanted. Obviously this isn't the DC fault, it's BIL's doing (he's the resident parent, ex SIL has the DC every other weekend and half holidays). But then afterwards they still descend on MIL for Christmas day and eat dinner and get more presents, all the while telling everyone how shit they think Christmas is. We just don't go over there on Christmas day any more because me and DP both find it so unbearable!!
I don't really care if people do or don't celebrate, or what they celebrate or how they celebrate, but the unbearable smugness combined with the absolute rubbishing of Christmas just grates my cheese. I keep wanting to say to BIL "well you might think Christmas is shit but at least my kids know what we are celebrating and why, and don't throw a tantrum if they don't get everything on their list, so NERRRRRRR". But I obviously won't because I'm not a dick. I'll just rant here instead.
