My daughter-in-law wants to bring her gay brother to our next family function. I’m not against gay people; it’s just that I don’t want it in my face or under my roof. The brother has a boyfriend, too, and he most likely would tag along if my daughter-in-law has her way. My son knows how I feel about the situation, but he insists that it is rude on my part not to allow his brother-in-law to come to family functions when other in-laws are welcomed. As far as I know, his wife doesn’t know that I disapprove of her brother. I don’t talk about him except to my husband and my son, and it is rare that I do say anything, except to say that I don’t want him in my home.

I don’t want to be mean. How do I politely ask my daughter-in-law to un-invite her brother to our family get-togethers?
