Most embarrassing thing I've ever said

Well, there's two that stand out. The first, which ended a friendship, was when I was at uni and my mate Joseph was dating this fairweather feminist. I said that fat people would get respect before trannies, and that wasn't considered a very PC thing to say. Then there's something I said while having lunch with the organiser of an Indian protest regarding university strikes back home. I asked which Indigenous groups were involved, being too dense to realise that Indians are an Indigenous group.
