OP - not calling you, or anyone else racist - the original joke about caravans was funny but it WAS on the line and non-PC: the way funny jokes often are! The title of the thread references a joke most of us found funny. But it’s probably best not to have an official title of the LI thread referencing caravans. If anyone finds it offensive, they can’t just scroll past and keep quiet, it’s in the title. I would ask to change it and just carry on with the banter. And let’s not insult each other just because we have different views.
(Probably inadequately explanation: unless the person literally owns or lives in a caravan, associating caravans with someone on the basis that they are from a traveller background is applying a stereotype. Like the example given earlier about an Indian contestant and a corner shop, or saying a Chinese contestant was picking out the chopsticks for his wedding list as soon as he saw the love of his life. It’s not being easily offended to point this out, it’s an understanding of how minorities feel when they are constantly associated with cultural features instead of treated like people. Everyone has different levels of sensitivity, right? Let’s not piss on each other because we think differently. Personally as an ethnic minority myself, i’m not offended but it does make me uncomfortable.)
