I don’t think they know how strongly we disagree with them to try to keep the peace. Our daughter and her husband know we don’t agree with them, but we just ignore the elephant in the room for the sake of the kids. We normally do separate family dinners and two Christmases to appease our daughter, as we love our grandchildren dearly and they should not miss out on family love because of their parents’ attitudes. He went to her wedding, came out shortly after that, and they have been on icy terms since. This breaks our hearts and hurts her brother so much, as they used to be so close as kids. My daughter had told us she won’t let her kids be around homosexuality and has not spoken to her brother since he came out. Our son is openly gay and dating a boy that we have known forever. We love the grandkids to bits, her husband not so much, but I don’t think he knows that. She has given us four grandkids (all under 6), with a fifth on the way.
But our daughter has developed some pretty extreme views since marrying a Christian pastor, and she had become a big part of the family Christian values movement.
