Anna and I spoke at UXCampAMS18 about "Cultural differences and their impact on design". We spoke on this topic at a meetup in our office and also at UX Camp Helsinki. We felt that this is a topic that needs discussion and what better place than UXCampAMS which sees the participation from a diverse set of passionate individuals! We tried to tweak the content in a way to evoke discussion throughout the talk to make it an engaging experience for everyone. The talk helped us get some feedback and also triggered interesting discussions. This helped us to iterate for the next occasions when we spoke on this topic.
UX Camp is a safe space to bring up topics for discussion with the community. As long as you are genuine about what you want to share and more importantly, learn, I would definitely encourage you to prepare for a session!
