I wish I could ignore it but I can't. The MIL used to host the family Christmas and gatherings, but is now elderly. For the last few years the BIL has done it. My issue is his house is filthy, kitchen is disgusting and we sit on clutter. Even with 20+ people. It's so embarrassing and no one will say anything. I've suggested we meet somewhere neutral but they won't. We don't live locally. DH doesn't see a problem either.
