My FIL is in his 70s and his health has been terrible for years (which he refuses to do anything about) so it's assumed by my DH and his family that FIL won't be around long (this is relevant)
He is incredibly old fashioned in his views. Or just pig-ignorant and getting away with it because his age means people assumed it's 'old fashioned'. I don't think his age is an excuse at all.
We're expecting a baby and bought some clothes at the weekend - one was a t-shirt, White with red stars on it.
DH said he wanted one in adults size for himself, cue FIL piping up that he would 'start worrying' about DH if he wore a t-shirt like that etc... Basically implying he's gay which FIL clearly thinks is a bad thing.
This is his favourite thing to say - he does it at every opportunity (usually including a limp wrist hand wave)
I am really struggling not to shut him up by saying something like "what would you be worried about FIL? Just his taste in t-shirts or the fact that he might like bum sex?" Or ask him why he thinks his son's sex life is any of his concern.
DH thinks you won't change his attitude and FIL will be dead by the time our baby is old enough to understand what he's saying.
I still don't like sitting by quietly when he comes out with this rubbish though
