My partner's parents will sometimes use racist phrasing when referring to people. I won't word it on here as it will cause offence. My kids are now getting to ages where they will ask, 'what does this mean?' etc. My partner and I have always corrected his parents when they have said racist terms, and on multiple occasions my partner has spoken to them about it away from the kids. You wouldn't believe how frequently things can come up in conversation (completely unnecessarily) for example a description of a shop cashier that is irrelevant to the story they are telling. I don't know how to go about this as we have tried to be direct with them. I don't know whether to simply tell my kids, 'your grandparents use words that are offensive and unkind and we shouldn't be using those words', because nothing else seems to stop them, it's like it's engrained in their language. Not that that is an excuse for it at all. Its got to change because we don't want our kids to be alone with their grandparents where myself or my partner aren't around to correct their language and call them out. Any advice appreciated please.
