Wife (29) does not want to inviter her brother (21) to visit us for Xmas, as he recently came out as gay.

He is 20, and went to university last year, and he recently came out via facebook. They doth don't have much family around the country, but are not that close. This year she's saying he's not invited as she doesn't really like the idea of him being around the kids (4M and 6M), but its not very chirstmasy to have a sinner near by according to her.

Should I just let her be, and maybe help him financlly book a train ticket to maybe his nan up north, I don't really care or know him well enough as he's been at school/university msot of the time.
