N.G.
I love noisy toys, they were my favorite as a kid and I definitely don't mind my kids having them. I do require them to use their noisy toys within reason- not when I'm on the phone, having a conversation, or we are watching television, etc.
My family tends to give really annoying toys as gifts as a joke and we all think it's funny.
I think you need to lighten up a bit. That's a lot of noisy toys to have around, put some of them up or donate some of them. Kids are kids and grandparents want to get the kids what THEY will like.
I actually hate it when family members or friends say stuff on facebook that they should say to me personally so I find that approach a little insensitive.
